You can keep a close eye on indoor air quality with the testo 445 climate measuring instrument: the allrounder can measure up to 6 parameters (with the appropriate probe), which can help you make a professional assessment of indoor air quality. The climate measuring instrument therefore supports you in adjusting and checking ventilation and air conditioning systems.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.The robust high-temperature/humidity probe (with a corresponding measuring instrument) is suitable for reliably determining the temperature and relative humidity even at high temperatures (up to +180 °C).

详情：
Use the robust high-temperature and humidity probe for reliable measurement of temperature and relative humidity. As the probe can be used at temperatures up to +180 °C, it also enables measurements to be taken in industrial exhaust air or in air-conditioning cabinets.Robust high-temperature/humidity probe (Ø 12 mm).
Note: you need a plug-in head cable (0430 0143) for this probe.
