The Testo 635-2 is an instrument capable of measuring air moisture, material equilibrium moisture and pressure dew point in compressed air systems. With this tool, moisture characteristics can be stored on internal memory, and analysed or displayed in graphics and tables.
The operator is also able to connect up to three temperature or humidity probes, and the instrument can automatically calculate the dew point difference between ambient air and the wall surface (e.g. when analysing moisture in ceilings and walls).
Some of the features of this model include...
- Displays dew point distance, as well as minimum, maximum and mean values
- Memory function (10,000 readings)
- PC software for data management and analysis
- Long-term and stable humidity sensor
- Backlit display and lightweight
- Radio probe for humidity and temperature
- Displays material moisture using user-defined characteristic curves
- Easy access to important functions via customisable profiles
- And the unit is IP54 rated
In addition to the instrument itself, this kit also includes a battery, calibration protocol, PC software and a USB data transfer cable.
