The Kestrel 4200 Pocket Air Flow Tracker has been designed for HVAC applications, allowing instant and accurate readings of air flow and environmental conditions whenever and wherever you are.
Ideal for HVAC, health & safety, facilities and maintenance engineers, the Kestrel 4200 offers a multitude of features to help monitor your environment in one single instrument - right in the palm of your hand.
The Kestrel 4200 combines all the features of the Kestrel 4000 and Kestrel 4100 and also makes the HVAC technicians job even easier with built-in wet bulb temperature and humidity ratio readings.
Like the Kestrel 4100, the Kestrel 4200 features automatic volume air flow readings. Simply enter the duct shape and dimensions, hold the Kestrel 4200 in the air stream and the volume air flow readings are displayed - no calculator required! With the convenient averaging mode, you can be sure the volume air flow readings are accurate in any airflow or duct size and shape.
Individual functions can be displayed in 3 different formats: current, minimum/maximum/average and chart. There are also 3 user screens, which can be customised to simultaneously display the 3 most appropriate functions for the application.
The Kestrel 4200 can be set up to log data automatically (as well as manually) at programmable intervals, in order to display a history of environmental information. Graphs display up to 1600 data points, the value, time and date of capture point can be shown. An optional interface is available to upload the data direct to a PC.
The display is easy to read with illumination for use in poor lighting conditions.
High precision jewel bearings and a lightweight impeller provide accurate air flow measurements (+/-3% of reading) and the ability to operate at speeds as low as 0.3 metres a second. The impeller is user-replaceable in case of damage, also ensuring high accuracy levels are maintained for life. An integral hard cover protects the impeller when not in use. A precision external thermistor sensor provides fast response temperature readings and accuracy of +/- 1°C. The 0.1 degree resolution of the display aids in determining when a consistent reading has been reached. A special housing protects the relative humidity sensor from contamination providing an accuracy of +/-3%.
The Kestrel 4200 Pocket Air Flow Tracker is as accurate and comprehensive as other instruments costing far more. On-screen customisation allows the technician to personalise their 4200.
The Kestrel 4200 is powered by two easily replaceable AAA batteries and has two power saving modes to prolong battery life. All text can be displayed in one of five different languages: English, French, German, Italian or Spanish.
