Thin humidity probe with built-in electronics, incl. 4 attachable Teflon protection caps for material moisture equilibrium measurement.
Materials which take in and retain or release water are described as hygroscopic materials.
Hygroscopic materials always try to form a moisture equilibrium with the surrounding air.
This principle is used to measure the moisture in material by measuring moisture equilibrium.
Ideally, moisture equilibrium is measured in a bore hole in the material.
To keep the bore hole as small as possible, a thin .16 in. humidity probe is used.
It should be protected from dirt by a Teflon cap during measurement. The bore hole is then simply sealed using sealing clay.
Based on the moisture equilibrium measured, Testo 635 automatically shows material moisture in % in the display.
Material moisture calculation is available for the following materials:
- High-insulation bricks
- Solid bricks
- Hard wood
- Soft wood
- Gas concrete
- Particle board
- Calcium sulphate floating screed
- Cement floating screed
- Lime sand brick
Materials are easy to select from the menu. Using the "Material" user profile, the material can be accessed directly at the touch at a button
Additional material characteristics can be stored in testo 635-2 using ComSoft.Features
