With fixed velocity probe incl. temperature measurement and telescope (max. 820 mm), battery and calibration protocol.
The compact testo 425 anemometer with permanently attached thermal
flow probe (probe head Ø 7.5 mm) incl. telescopic handle. Volume flow is
shown directly in the display. Accurate volume flow calculation thanks
to easy input of duct area. In addition, it is also possible to switch
to the current temperature reading. Timed and multi-point mean
calculation provide information on mean volume flow, flow speed and
temperature reading. Min/max values can also be shown in the display.
The Hold function makes it possible to freeze current readings in the
