Kestrel 4200 Impeller Anemometer, 40m/s Max, Measures Air Flow

This Bluetooth version of the Kestrel 4200 has an orange case. The Kestrel 4200 combines the features of the Kestrel 4000 with built-in wet bulb temperature and humidity ratio readings. Users enter the duct shape and dimensions, hold the Kestrel 4200 in the air stream and read the volume air flow off the display - no calculator is required. The convenient averaging mode ensures accuracy in any air flow or duct size and shape. Individual functions can be displayed in 3 different formats: current; minimum/maximum/average; chart. There are 3 user screens that can be customised to simultaneously display the 3 most appropriate functions for the application. The Kestrel 4200 can be used manually and set up to log data automatically at programmable intervals, in order to display a history of environmental information. Graphs display up to 3600 data points. The value, time and date of capture point can be shown.
