Testo 405 Thermo-Anemometer (Metric Only)

The Testo 405 measures air flow velocity, volume flow, and temperature.  Its extendable telescope makes the 405 ideal for measuring air flow velocity in ducts. 

Low air flow velocities are the Testo 405's specialty, so the air flow source in a drafty window can also be efficiently located and measured.  The display is able to rotate, which makes reading the measurements quick and easy.
