The Testo 405i (0560 1405) Hot-Wire Anemometer 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 inches for easy in-duct testing. You can reliably determine timed and multi-point flow traverses.
Measures air velocity, volume flow, and temperature
Small diameter (< 0.5 in.) and telescopic shaft ideal for in-duct air flow measurements
Automatically calculates volume flow if duct dimensions are entered
Reliably determines timed and multi-point flow traverses
Suitable for performing air duct leakage tests
