The compact Testo 425 anemometer has a permanently attached thermal flow probe and telescopic handle. The volume flow is shown directly in the display. Accurate volume flow calculations are achieved thanks to the easy input of the air duck area. It is also possible to switch to the current temperature reading. The timed and multipoint mean calculations provide information on mean volume flow, flow speed and temperature. Max and Min values can also be shown on the display. Also the hold function makes it possible to freeze current readings in the display.
