-
Measurement of air velocity, volumetric flow and air temperature
-
For measurements in ventilation ducts and in rooms
-
Particularly precise in the range between 0 and 2 m/s
-
Telescope extendible to 300 mm
Use the testo 405 thermal anemometer to measure air velocity, volumetric flow and air temperature. It is suitable for carrying out quick check measurements in ventilation ducts and for measuring the air velocity in rooms for indoor air quality, e.g. at draughty windows.
