Product Overview

Wildland firefighters train to withstand the challenge of heavy exertion in extreme conditions. Extreme heat is a constant companion, and protective gear exacerbates the physical strain on a firefighter's body. Building heat acclimatization is a critical component of training, but doing so without incurring heat illness or injury is equally critical and challenging. Heat injury is a constant danger with many incidents of heat related illness occurring every year. Heat illness prevention programs recommend measuring Wet Bulb Globe Temperature (WBGT) and implementing ACGIH work/recovery and hydration guidelines. WBGT is a much more complete measure of heat stress for the firefighter because it includes the effects of the radiant heat of the sun, fire, or hot surfaces. The Kestrel Fire Weather Meter PRO WBGT adds the WBGT measurement to the full capability of the Fire Weather Meter Pro – making it the complete tool for monitoring WBGT and fire weather during training or operations. With pre-programmed ACGIH guidelines and alert settings to indicate when conditions have become extremely unsafe, the Kestrel Fire Weather Meter PRO with WBGT is the ultimate tool for increasing the safety of your crew.

Unlike other WBGT meters on the market, the Kestrel 5400 Fire Weather Pro WBGT is also a rugged, compact and easy-to-use portable weather station. Clip the Kestrel 5400 into the secure tripod vane mount to set up a weather and heat safety monitoring station in seconds. Measure wind speed, direction, temperature, humidity, pressure, dew point, elevation, density altitude, PIG, FDFM and more. In addition to measuring the current environmental conditions, the Kestrel 5400 Fire Weather Pro tracks and logs over 10,000 sets of time-stamped data. Your data log can be transferred to an iOS/Android device wirelessly with the LiNK wireless communication option and free Kestrel LiNK app, then exported and shared via email with ease. Data can also be transfered to a Windows/Mac device with either the accessory Kestrel LiNK Dongle or waterproof USB Data Transfer Cable (both sold separately).

The Kestrel 5400 Fire Weather Meter Pro WBGT offers a large, high-resolution and contrast display and easy font readability. It also includes a built-in dual color backlight, extra-strong polycarbonate lens and AA battery operation, along with LiNK iOS and Android wireless connectivity and app support. Like all Kestrel meters, the Kestrel 5400 Fire Weather Pro WBGT is drop-proof, dust-proof, waterproof and able to withstand harsh environments without damage – so it can so it can work as hard as you do.

Kestrels have been put to the test in some of the harshest conditions on the planet. U.S. Special Forces, combat weather teams, wildland firefighters, smoke jumpers, Mt. Everest expeditions and auto pit crews are just a few who rely on a Kestrel to provide them with the crucial environmental data they need. There truly is no comparable environmental safety monitoring tool on the market. Adopt best safety practices for your team or workplace and add a Kestrel Heat Stress Tracker to your toolkit.

1 inch|25 mm diameter impeller with precision axle and low-friction Zytel® bearings. Startup speed stated as lower limit, readings may be taken down to 0.4 m/s | 79 ft/min| 1.5 km/h | .9 mph | .8 kt after impeller startup. Off-axis accuracy -1% @ 5° off-axis; -2% @ 10°; -3% @ 15°. Calibration drift < 1% after 100 hours use at 16 MPH | 7 m/s. Replacement impeller (NK PN-0801) field installs without tools (US Patent 5,783,753). Wind speed calibration and testing should be done with triangle on impeller located at the top front face of the Kestrel. Measuring wind speeds above 60 m/s / 134.2 mph can damage the impeller.

Airflow of 2.2 mph|1 m/s or greater provides fastest response and reduction of insolation effect. For greatest accuracy, avoid direct sunlight on the temperature sensor and prolonged sunlight exposure to the unit in low airflow conditions. Calibration drift is negligible for the life of the product. For further details, see Display & Battery Operational Temperature Limits
Relative Humidity ±2%RH 0.1 %RH 10 to 90% 25°C non-condensing To achieve stated accuracy, unit must be permitted to equilibrate to external temperature when exposed to large, rapid temperature changes and be kept out of direct sunlight. Calibration drift is typically less than ±0.25% per year.

Monolithic silicon piezoresistive pressure sensor with second-order temperature correction. Between 1100–1200 mbar, unit will operate with reduced accuracy. Sensor may not operate above 1200 mbar and can be damaged above 6,000 mbar or below 10 mbar. Calibration drift is negligible for the life of the product.
Compass ±5°
1/16th Cardinal Scale
0 to 360° 2-axis solid-state magnetoresistive sensor mounted perpendicular to unit plane. Accuracy of sensor dependent upon unit's vertical position. Self-calibration routine eliminates magnetic error from batteries or unit and must be run after every full power-down (battery removal or change). Readout indicates direction to which the back of the unit is pointed when held in a vertical orientation. Declination/variation adjustable for True North readout.
