Probes and printer must be ordered separately.

Provides quick and easy Humidity, Equilibrium Moisture, and Pressure Dew Point measurements. Up to 3 Temperature or Humidity probes can be displayed wirelessly. Selectable user profiles, so you can allow function buttons allocated to a specified application and menu guide facilitate intuitive operation. Material moisture can be displayed directly using special probes. To analyse humidity on ceilings and walls, Testo 635 shows the dewpoint difference between ambient air and wall surface.
