The testo 608-H2 thermohygrometer enables you to have a continuous display of the current temperature and humidity values. It is also integrated with visual alarm that is activated when a threshold is exceeded.
The testo 635-2 temperature and humidity measuring instrument enables you to measure the temperature, air humidity and dew point – in compressed air as well. Integrated memory and software makes it more reliable.
The testo 645 humidity/temperature measuring instrument automatically indicates the measurement parameters of relative humidity, absolute humidity, dew point, degree of humidity, enthalpy and temperature at the touch of a button.
