The probe is used for the specific measurement of combustion air temperature within the context of flue gas or particulate matter measurements.

The probe is used for the targeted measurement of combustion air temperature in the context of flue gas or fine particle measurements.

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 5 m long extension cable is best suited for use between plug-in head cable and instrument.
