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. Precision probes up to 140°F tpd are available for checking pressure dewpoint in compressed air systems.
Wireless probes offer many advantages over traditional cable or integrated probes. There is no risk of damaging or tangling wires or cables and measurements up to 65' are possible. The optional, easily installed wireless module can be retrofitted at any time. For wireless use, a wireless module, wireless handle, and wireless probe is required. These are available as accessories.
