Testo 416 - Small Vane Anemometer

Brand: Testo

The Testo 416 small vane anemometer (air flow meter) accurately and easily measures air velocity and volume flow (CFM) for in-duct and a variety of HVAC applications above 120 fpm.

As vane technology is inherently air density independent, the Testo 416 handheld digital vane anemometer provides repeatable and reliable readings test after test.

The Testo 416 is an easy to use small vane anemometer with an attached vane probe on a telescoping handle to measure CFM in air ducts.

This handheld digital vane anemometer allows you to switch between volume flow and velocity readings quickly.
