hot-wire anemometer / hand-held / wireless

he testo 405i Smart Probe hot-wire anemometer 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.

Key Features:

Measures air velocity, volume flow, and temperature
Measures in-duct air flow and automatically calculates volume flow (enter duct dimensions simply)
Small dia. (<0.5?) and 15? telescopic shaft length is ideal for in-duct flow averaging and timed traverse
Perform air duct leakage tests
