UEi DAFM4 Digital Anemometer/ Psychrometer, 99 to 3937 ft/min

The DAFM4 is the tool for all your airflow measurement needs. With the DAFM4 you can directly capture air temperature, relative humidity, and air velocity. It also calculates wet-bulb temperature, dew point temperature, and air volume. Enter duct dimensions for live or timed average of air-flow in CFM (or CMM), or use the effective area of a grill for outlet volume measurements.

Air volume is displayed in real-time, or choose a timed average with start/stop capabilities to traverse ductwork.
