DAFM4 • DIGITAL AIR FLOW METER

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.

• 0.7” small diameter air vane on
39” long telescoping probe

• Hard carrying case

• 9V battery

• Manual
