  • Dual Probe Measurement
  • Measurement of air moisture, material equilibrium moisture, pressure dew point
  • U – Value probe connection
  • Internal Memory 10,000 Readings

The Testo 635-2 is an instrument designed for measuring air moisture, material equilibrium moisture and pressure dewpoint in compressed air systems. Moisture characteristics can be recorded in the instrument memory and analysed and displayed in graphics or tables. Precision probes up to -60°C tpd are available to check pressure dewpoint in compressed air systems.

Product Description

Key Features

  • Instrument memory for up to 10,000 readings
  • PC software for analysis, filing and documentation of measurement data
  • Measurement of air moisture, material equilibrium moisture, pressure dew point
  • Protection class IP54
  • Direct display of material moisture due to freely settable characteristics curves (based on equilibrium humidity)
  • Storage of single measurements or measurement series by measurement location
  • Fast access to the most important functions via user profiles
  • U-value probe connection option

Rugged, practical, easy to use

In addition to all the other measurements, the testo 635-2 temperature and moisture meter can also display min, max and mean values and calculate the dew point difference between the indoor air and the surface of the wall. This allows you to analyze levels of moisture at ceilings and walls. Individually configured characteristic curves ensure that the material moisture content is displayed reliably.

Both the meter and the menu guide are simple and comfortable to use. A backlit display allows you to read the measurements in the dark or poor lighting and a strong protective case protects the meter effectively against any accidental knocks and bumps.

Saving, transferring and printing out data

Save measuring sites and allocate the measuring data to the relevant site. Create individual user profiles to perform parallel long-term and material moisture measurements. Save up to 10,000 readings – individual measurements and measurement series – to your meter. The USB cable in the scope of supply can be used to connect your moisture meter to your PC or laptop and the software allows you to log and archive your measuring data comfortably and easily.
