The testo 405i Smart Probe is a wireless instrument for measuring air flow velocity, temperature, and volume flow. It is equipped with a telescopic shaft, which extends to 15” for easy in-duct testing. You can reliably determine timed and multipoint flow traverses.
testo 405i Features:
Measures air velocity, volume flow, and temperature
Measures in-duct air flow, and automatically calculates volume flow
Small diameter (<0.5”) and 15” telescopic shaft length is ideal for in-duct flow averaging and timed traverse
Perform air duct leakage tests
