The safety of crop spraying is reliant on measurements of relative humidity, wind speed and wind direction, these measurements are also critical for maximising the effectiveness of the spraying process. This is also a heavily regulated area with many regions specifying maximum permitted wind speed when spraying to minimise spray drift.
Every single Kestrel model offers fast and certified-accurate wind speed measurements in a unit that fits conveniently into your pocket, making it easy to be in full regulatory compliance. In hot, dry conditions, evaporation can send your expensive chemicals uselessly into the air rather than onto your crops. In these conditions, selecting an appropriate nozzle and increasing the spray droplet size can minimize costly evaporation. Kestrel models are available to measure dry bulb temperature, wet bulb temperature, Delta T, relative humidity and dew point temperature. Every Kestrel humidity measurement uses our patented fast-acting humidity sensor with accuracy guaranteed through a two-point calibration. Wet bulb temperature is pressure-corrected to ensure accuracy even at high altitudes and low humidity.
If your application requires documentation of the weather conditions, use the Kestrel 5000's 2000-point memory to conveniently store all environmental information with the single press of a button, and later upload your stored data to a computer to create a log of spraying conditions (requires optional interface).
Environmental control is key to ensure the health of livestock. Effective ventilation and temperature and humidity control of livestock facilities is fundamental and can reduce disease and prevent stock loss, as well as improve your rate of gain and feed-conversion efficiency.
A Kestrel 3000 Pocket Weather Meter allows you to measure the key parameters - air velocity, temperature, and relative humidity and due to its compact size this can be done right next to the livestock and the environment they are experiencing. Complete with an optional rugged carry case that can easily be clipped to your belt, the Kestrel 3000 will always be close at hand to ensure you can complete spot checks efficiently whilst improving your stocks safety and health.
Vineyard managers need essential environmental conditions data to maximise the harvest and minimise vine damage. The Kestrel 3000 monitors the key parameters of wind speed, air temperature, relative humidity and dew point right next to the vine. This helps determine the frost protection requirements in the key spring and autumn seasons. If the air is dry (low dew point) heat loss will be greater than when the air is moist, and the threat of a radiation freeze goes up. Dew point and temperature also affect leaf wetness, which influences the development of downy mildew. The Kestrel's wind speed readings ensure that spraying is done safely and effectively during appropriate environmental conditions.
A Kestrel Pocket Weather Meter is also a valuable tool when planning your vineyard. Tracking conditions at potential vine locations can help you develop an accurate understanding of your property's microclimates and select the varietals and growing sites that will ensure success.
Choosing the best environmental conditions to harvest crops maximises the harvest and the crop quality. The Kestrel Pocket Weather Meter helps farmers track the current and predicted climatic conditions. Whatever the crop you grow, a Kestrel Pocket Weather Meter (such as the Kestrel 3500) makes it simple to monitor field conditions from your pocket in real-time to pinpoint the ideal conditions for maximising your harvest and crop quality. Rugged, portable and simple to use, it also comes at an affordable price.
Livestock Heat & Cold Monitoring
Heat stress can cause reduced productivity and even death in livestock. The effects of severe heat stress are often seen in the form of reduced reproductive performance, reduced daily weight gain and reduced milk production. By using a Kestrel to monitor temperature and humidity, and referring to the heat index appropriate for your livestock (indices exist for cattle, swine, turkeys and laying hens), a farmer can take necessary cooling measures in time. Cooling measures include increasing ventilation, making plenty of drinking water available, misting the animals, avoiding transport and movement, and withdrawing feed.
Wind chill is equally important in the winter. A cow's energy requirements are estimated to increase 1% for each degree the wind chill is below 32°F, and the effect is even more severe for a wet cow. These increased energy requirements have to be made up in additional feed or the animals will fail to thrive.
Perfect for temporary airfields or remote airfields, FlexiMet Wind and FlexiMet WX systems are fast to install and ensure personnel on the ground can provide needed landing zone weather data. Data logging functionality delivers long term records ideal for analysis prior to developing a remote or temporary airfield.
Other applications include wind and weather analysis for parachute drop zones, local flying clubs and hot air ballooning events.
Aircraft Hanger Door Operating Systems
FlexiWind systems with a WS-15A Display unit have been used extensively to monitor wind speed and direction to ensure safe operation of hangar doors.
Hangar doors often have high wind speed limits and operators must ensure they work within these. The FlexiWind systems with WS-15A displays not only allow for remote viewing and data logging of wind speed and direction data but there is also a single relay switch within the WS-15A display. This allows the hangar doors to be locked down when a defined wind speed limit is met.
Ideal for harsh remote locations the FlexiMet Wind and FlexiMet WX systems utilise Gill ultrasonic technology guaranteeing accurate data with minimal maintenance. Linked to the IP65 rated WS-15A display, the system is often used as a secondary system, being able to operate locally from a 12V power supply.
The MetPak Pro sensor allows extra inputs making it ideal for remote environmental data buoy monitoring. The MetPak Pro measures the standard MetPak weather parameters including wind speed, wind direction, air temperature, relative humidity, dew point and barometric pressure. In addition it has the facility for extra inputs to be added enabling sea temperature, precipitation, light readings and depth readings to be acquired.
RPR Ltd can supply the sensor alone or work with the relevant authorities to deliver a complete standalone system. The GBR sailing and canoe teams have both used RPR Ltd's systems for medium to long term monitoring of event locations.
School Weather Stations
RPR Ltd have been selling weather stations to Schools and other Education establishments for many years. The FlexiMet Wind and FlexiMet WX systems deliver extremely accurate data that is ideal for research purposes. With a power requirement of only 12V, they are quick and easy to install even in remote locations far away from mains power.
The systems will store all the data locally on the SpaceLogger data logger and from here it can be manually transferred to PC using the SD memory card or viewed live on the PC if the system is within a Wi-Fi network. Data is captured and held within a CSV file format making it easy to view within standard Microsoft programs such as Excel.
RPR Ltd can lease, rent or sell the systems depending on the customer requirements.
Fire-fighting / Emergency Response Vehicles
To understand air movements and deliver accurate plume modelling it is essential to observe real time environmental conditions.
Richard Paul Russell Ltd have developed a complete weather station utilising WindSonic and MetPak technology that can be fitted to first responders vehicles giving instantaneous weather data within seconds of arrival. The system can be mounted directly onto a vehicle or positioned remotely using a tripod or pole mounting fixed to a structure.
The FlexiMet Wind 1 system using WindSonic technology will deliver wind speed and direction whilst the FlexiMet WX 1 with MetPak technology will monitor additional environmental parameters including temperature, humidity, barometric pressure and dew point. You can add additional functionality to the systems with a bespoke easily mountable display to view instant readings, whilst data logging functionality ensures long term data retrieval for report writing and post event analysis.
Now every first responder vehicle can carry the equipment required to analyse and log the data to ensure the safe deployment of personnel.
Remote Weather Data Collection
SpaceLoggers have been widely deployed for many varied outdoor environmental monitoring applications, including climatic monitoring as well as indoor monitoring within offices, workplaces, warehouses, schools and other premises.
SpaceLoggers are designed to function remotely requiring only 7-30V DC power. The data is stored on an SD memory card so no PC hook-up is required in the field. In the case of the SpaceLogger W8 Wireless data logger, wind speed and direction can be relayed directly to PC over the local Wi-Fi network.
The SpaceLogger S10 is a hugely versatile data logger and may be configured for virtually any sensor outputting RS232 data, including devices requiring polling or handshake to enable data output.
Mapping Conditions & Life on the Sea Bed
SpaceLogger S10 data loggers have been utilised to map the conditions and life on the ocean floor. SpaceLogger S10 data loggers were being towed at depths of 3000 metres whilst taking recordings of CTD (water conductivity, temperature and depth).
The SpaceLogger S10 data loggers were part of the equipment on three 3000 metre depth rated ‘pods' along with batteries, video processing equipment and control electronics.
Marcus Shirley of Mr ROV, a member of the research team, confirmed back to us:
With increased awareness and monitoring of air quality there is a demand for accurate sensing equipment that is reliable, low maintenance and durable. Richard Paul Russell Ltd supply complete weather system solutions that can be easily transported and fixed to structures using a bespoke mounting system or remotely positioned using a tripod.
The Richard Paul Russell Ltd systems use ultrasonic WindSonic and MetPak technology which are pre calibrated and have no moving mechanical parts thus require very little on-going maintenance, reducing operational costs.
Understanding weather conditions such as wind speed and direction, temperature and humidity is essential when trying to analyse pollution the environmental conditions and deliver plume modelling. Commonly monitoring of pollution and environmental conditions takes place in extremely varied locations, from inner cities to remote rural areas.
The FlexiMet system from Richard Paul Russell Ltd uses the Gill MetPak sensor with an integrated WindSonic ultrasonic wind sensor for high accuracy wind speed and direction measurement combined with air temperature, relative humidity, dew point and barometric pressure readings. When used remotely the system can be powered by battery and solar power with the SpaceLogger W10 data logger acquiring the data into a CSV file for easy download to PC. If the system is held within a Wi-Fi network the SpaceLogger W8 Wireless data logger will allow 'real time' viewing of the data on PC or via the Weather-File website.
|Fire-fighting & Emergency Response|
The Kestrel range has been used by fire-fighters and emergency response teams for many years. The Kestrel range has a model that meets all requirements from wildland fire-fighting to search and rescue to hazardous materials response.
Preferred models are the Kestrel 3000 and Kestrel 3500 delivering fire behaviour prediction from wind speed combined with temperature, relative humidity, dew point and wet bulb temperature. This information is key to monitoring heat stress and avoiding heat injury or death of personnel.
Search and Rescue teams often require additional density altitude with wind readings data to ensure rescue craft and personnel have exact weather conditions ensuring safe operations. The Kestrel 5000 delivers barometric pressure, pressure trend, altitude, humidity, dew point and heat stress readings combined with other parameters in an extremely compact and portable design ensuring quick data retrieval that can be communicated to rescue teams, aircraft and dog team leaders.
HAZMAT teams can rely on the Kestrel 5400 with Bluetooth and portable vane mount as a complete weather kit able to measure all the parameters required for plume modelling whether CAMEO/ALOHA or PEAC. Personnel dressed in heavy protective clothing are safeguarded from the potential effect of heat stress with this variable being specifically measured. Using the Bluetooth data transfer facility all data can be logged and analysed before during and after personnel deployment.
|Health & Safety Monitoring|
Working at Height
The Health and Safety Executive in their health and safety in roof work paper make specific reference to wind and weather conditions stating that weather conditions should be considered when planning any work at height. Obviously wind, rain, ice or snow can have a direct impact on how secure a foot holding will be.
HSE Advises Maximum Wind Speed
1. You should anticipate adverse weather conditions and take suitable precautions. The Work at Height Regulations 2005 specifically require that weather conditions be considered when planning any work at height. Rain, ice or snow can turn a secure footing into a skating rink. A roof should always be inspected before work starts to see if conditions have changed and to check whether it is safe to work.
2. A sudden gust of wind can lead to loss of balance. Roof sheets and, in some circumstances, roofing membrane should not be fixed in windy weather as people can easily be thrown off-balance while carrying a sheet up to or on the roof, particularly when handling large sheeting materials during work on industrial buildings.
3. It is not only in industrial roofing that care must be taken in windy conditions. A slater or tiler cannot work safely in high winds and a roll of roofing membrane can become mobile if it is caught by the wind. On flat roofs, materials such as felts are equally affected and the effect of high wind upon hot bitumen when it is being poured can be extremely dangerous.
4. When deciding whether to continue or suspend work, consider:
5. A competent contractor should use a hand-held anemometer to measure wind speed if large sheets are being handled.
6. The Beaufort scale (Table 2) gives descriptions of how trees, smoke etc will behave at certain wind speeds.
Laboratory Equipment with RS232 Output
Much laboratory equipment is supplied with an RS232 output. Where continuous connection to a PC is impractical a SpaceLogger can offer a dedicated data logging solution for short or long term monitoring.
The SpaceLogger S10 is readily configured to record the output from numerous instruments and devices producing time-stamped records in .CSV file format.
SpaceLoggers are commonly used for recording cycle records from autoclave machines. They provide a cost effective and efficient way to monitor equipment with an RS232 output including weighing scales, refrigerators, freezers and storage rooms.
The SpaceLogger T10 model is ideal for balances or analysers with a print command and RS232 output and will keep a text record identical to the paper print-out. This file can be read using Notepad or similar.
|Marine, Ships & Harbours|
Dockside cranes can be exposed to the worst weather conditions and as such are susceptible to wind related damage and potential collapse. Operators need clear and accurate wind data delivered to the cab and monitored remotely to ensure they work within guidelines.
Richard Paul Russell Ltd has developed specific wind systems for crane use. The systems utilise a Gill ultrasonic sensor mounted high on the crane jib / boom. This is then linked to a WS-15A display in the cab that has high and low alarm settings ensuring an audible or visual alarm is activated when the wind speed reaches the maximum allowed.
The wind data is recorded using the SpaceLogger W10 or SpaceLogger W8 Wireless data loggers providing date and time stamped data for operator records. In the case of the SpaceLogger W8 Wireless data logger, wind speed and direction can be relayed directly to a site office PC and viewed live using our WeatherFile website.

The system delivers a maintenance free, robust and highly accurate solution for local weather information. Essential data for harbour authorities, visiting ships and recreational water sport participants.
Missile Trajectory Prediction
The RPR Ltd FlexiMet WX systems supply the accurate meteorological data required accurately predict ballistic trajectories within the atmosphere.
A projectile moving through the air is effected by a number of forces including wind, temperature, barometric pressure, and humidity, so accurate monitoring of all weather parameters is essential.
Accurate observation and measurement of surface wind at UAV sites is essential to ensure correct and successful launch and landings. FlexiMet Wind systems allow data to be gathered on site from various locations and analysed.
Because the size and design of UAV's varies greatly, knowing the surface wind conditions is critical to ensure control of the UAV is maintained. Any deviation from the planned flight path can pose a safety risk to ground crew and could result in serious damage to or total loss of the aircraft.
Recently multiple Gill WindSonic sensors have been connected at varying heights with data being monitored via SpaceLogger data loggers giving essential information for post launch and pre landing flight.
Temporary or Remote Air Fields
Recent applications have seen multiple WindSonic sensors at varying heights gathering data via SpaceLogger data loggers determining the variation in wind velocity from ground level upwards.

Both versions also come with an option for integrated Bluetooth technology offering the ultimate in portable and accurate environmental data. Now, both real-time and logged data can be transferred wirelessly and automatically to a laptop or PDA, making a Kestrel the perfect tool for virtually any job that requires quick and reliable data.
Pete Moore from Shooting Sports Magazine reviews the
Kestrel 2500NV weather meter
"If accurate shooting is your goal then you need to have all bases covered, consider a wind meter ... "
"... I approach my hunting by ensuring I have all the data and the right items I need to make the shot count every time... a chance to try out a wind meter was a bit of a revelation and now I know what I have been missing.
For me the real revelation was to know the actual wind speed, followed by the ability to get high, low and average readings quickly and apply them to a firing solution. The biggest surprise was how far out my eyeball methods of judging the speed were."
• If you take your shooting seriously this is an essential item

Competitive archers rely on their ability to compensate for the wind conditions, as the wind applies pressure on the bow it will determine greatly the arrows flight direction and rate of fall.
A Kestrel 1000 offers a simple and accurate solution providing current wind speed, average wind speed and maximum gust data in a pocket sized device that can be used in hand or fixed to a collapsible compact tripod with a vane mount.
The Kestrel 1000 is the perfect solution whilst practicing to learn how varying wind conditions impact on the arrows flight path and during competition to ensure an archer reads conditions correctly and compensates accordingly
Academic research, product development, testing and analysis all require a high level of accuracy along with convenient data storage.
SpaceLoggers have been used extensively for projects including sub-sea condition research, wind farm site analysis, pollution and noise monitoring and road traffic analysis, particularly where equipment is remote or space or power at a premium.
The SpaceLogger S10 for example offers a versatile solution to gathering data from numerous devices with RS232 output when it would be impractical to have direct link to PC. The SpaceLogger S10 connects directly to up to two RS232 data inputs, the data is stored on to an SD memory card that can be easily transferred to PC.
The SpaceLogger A10 will take up to 2 4-20mA inputs as well as an RS232 input, converting all to a combined, time-stamped serial data output and .CSV file.
Sailing Schools, Clubs, Marinas, Coaching & Race Management
Sailing and Yacht clubs require accurate wind data linked to an in-club display. Richard Paul Russell Ltd has developed a cost effective accurate solution. The FlexiMet Wind 1 system combines ultrasonic WindSonic technology with a tailor made software package that delivers a graphical display of real time and historical wind conditions, including current wind speed, average wind speed, maximum gust and direction straight into the club house. Combine this with MetPak technology and you can supply additional temperature, wind chill, humidity, barometric pressure and dew point measurements.
The systems can be remotely positioned with radio links delivering a constant data feed or by cable depending on distance. If you require a separate display remotely, e.g. your starting hut is positioned away from the club house display, the WS-15A Display provides a compact robust cost effective solution.
All the data can be logged using the SpaceLogger W10 (WindLogger) a compact unit that requires low power it will date and time stamp your data direct onto SD card for later analysis. The SpaceLogger W8 Wireless option will allow live viewing of the data via our WeatherFile website.
Golfers and golf course management take an active interest in the weather conditions. Temperature, Wind speed and direction measurements linked with precipitation readings form the basis of informed decisions regarding when to spray the course or determining the areas that could be susceptible to flooding. All this information can be data logged ensuring useful long term reporting, taking the guess work out of golf course care and management and useful for risk assessment linked to wind speed and direction.
The WeatherFile software delivers a professional display within the clubhouse or over the internet giving golfers real time information, helping them to decide on the correct clothing or when to sneak in that après work round.
Once installed the Richard Paul Russell Ltd system requires virtually no maintenance due to there being no moving parts and unlike a traditional cup and vane wind system it won't stop when a bird lands on it.
Sports stadium management and visitors utilise local weather information for many reasons. Officials will use it to determine whether to cancel events due to weather conditions and facility managers can rely on the weather data to determine heating and cooling plans. Grounds and maintenance crews will utilise the information to determine mowing, planting and watering schedules, and research and educational establishments can incorporate weather station and weather data into their coursework.
The information is invaluable for coaches and athletes to evaluate performance and the impact of environmental conditions on individuals.
Richard Paul Russell Ltd can supply systems that simply monitor trackside wind conditions or develop full weather stations linked to our SpaceLogger W10 or SpaceLogger W8 Wireless data loggers, WS-15A display or WeatherFile website for real time viewing of conditions and long term data gathering for later analysis.

Recording Of Sports Venue, Athlete & Equipment Performance Data
Capturing environmental data and analysing it is key to the training and development of athletes and coaches.
SpaceLogger W10 and SpaceLogger W8 Wireless data loggers allow remote capture of weather data in the field, on the water or track-side in the sports stadium. As part of a complete FlexiMet Wind or FlexiMet WX Weather station the SpaceLogger will record all data that can then be transferred either manually to PC using the SD card or viewed in real-time on PC when using the SpaceLogger W8 Wireless data logger.
For monitoring other athlete performance data, a SpaceLogger S10 can be configured for virtually any equipment with RS232 output offering a simple solution to add data logging function to existing or new systems.
SpaceLogger have been deployed at recent Olympic & World Championship venues to provide better understanding of the local conditions to ensure teams have the best information to make critical decisions which may make the difference in achieving a medal.
