DAFM4, Digital Airflow with Humidity Tester

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.
