    Testo 625 Thermohygrometer

    The Testo 625 Thermohygrometer measures air temperature from -10˚C to 60˚C with an accuracy of ±0.5˚C and a resolution of 0.1˚C. Humidity can also be measured between 0 and 100% RH with ±2.5% RH and a resolution of 0.1% via the plug-in probe head. A radio module or connecting cable (sold separately) can be used to take readings from awkward places. It is also possible to measure surface temperature over a maximum range of -200˚C to 1370˚C when connected to an optional type K thermocouple.

    Readings are displayed on the Testo 625’s backlit digital screen alongside a battery-level indication. The data hold function freezes the measurement value and it is possible to view wet bulb temperature or dew point in addition to humidity and temperature. The Testo 625 has a 70-hour battery life and comes supplied with a 9V battery and calibration protocol.
