Testo® Robust humidity sensor

Connected to the testo 635 humidity and temperature meter, the robust humidity sensor measures relative humidity and temperature and in storage, cold storage and work rooms or in air conditioning/ventilation ducts. In addition, a material compensation humidity measurement can be performed. For this purpose, the function for calculating the H2O content in the meter must be activated and the material of the object to be measured must be set (anhydrite flowing screed; cement flowing screed; sand-lime brick, concrete, highly insulating brick, solid brick, hardwood, softwood, aerated concrete, pressboard). The sensor can also be connected to the measuring instruments testo 435-2 and testo 435-4 (however, without being able to measure the material compensation moisture).
