Testo 416 Small Vane Anemometer

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.

Testo 417 Large Vane Anemometer

With readings of up to 4,000 fpm, the testo 417 rotating vane anemometer is ideal for collecting air velocity, CFM, and temperature measurements at supply and return grills. Having a larger vane, this air flow meter can cover a larger surface area, ensuring accurate measurements with each use.

Testo 425 Hot Wire Anemometer

Confirm cubic feet per minute (CFM) when conducting duct testing as well as easily switch between flow and temperature readings. The telescoping handle of the thermal probe on this CFM meter makes it easy to reach ductwork above your head.
