The testo 925 temperature measuring instrument is our all-rounder for temperature measurement in heating engineering, the sanitation sector and refrigeration and air conditioning technology. Take advantage of the thermocouple technology of the attachable temperature probes (type K thermocouple) with this temperature measuring instrument. It enables fast temperature checks and a large temperature measuring range from -50 to +1000 °C (the measuring range is dependent on the probe selected).
testo 925 temperature measuring instrument, including batteries and calibration protocol.
Note: the temperature measuring instrument requires a probe for commissioning (not included in the scope of delivery).
