The compact Testo 416 rotating vane anemometer has a permanently attached 16mm vane probe with telescopic handle. This makes the instrument ideal for spot measurements in ductwork systems.

In addition to air velocity measurements air volume flow can be shown directly in the display by entering the duct parameters via the menu options. Timed and multi-point mean calculation can also provide information on mean volume flow. Min/max values can additionally be shown along with a hold function that enables you to freeze readings.
