Testo 635 is a universal laboratory meter for measuring temperature and humidity with internal memory and PC software, USB cable for data transmission as well as a battery and calibration protocol.
The device allows precise reading of air humidity, building material humidity and pressure dew point in compressed air systems.
The meter's memory can store the humidity readings taken and also analyze them in the form of tables and graphs. Up to 3 temperature or humidity probes can be connected to the testo 635 simultaneously.
The Testo 635-1 kit includes: a humidity/temperature measuring instrument, along with a battery and calibration certificate
