The Tramex RWS-DACH moisture meter operates on the principle of measuring apparent electrical resistance. This means that a harmless, non-destructive, low-frequency signal is transmitted from two electrodes in the device’s base through the surface of the material being tested and into the material itself.
To measure or detect moisture, press the rubber base of the device against the material being tested. The detection signals emitted by the device penetrate the material being tested to a depth of approximately 10 cm, depending on the mode, the selected sensitivity range, and the material being tested. The small current flowing through the field is inversely proportional to the material’s apparent resistance. This current measures the change in electrical resistance caused by moisture content. This change is read by the RWS-DACH instantly
and continuously displayed on a large, clear screen that shows comparable readings on a reference scale from 0 to 100.
Application:
- multi-layer roofs,
- metal-free coatings,
- coverings made of spray foam,
- exterior wall finishing systems,
- tiles,
- gypsum walls,
- brick,
- wood.
Properties:
- For detecting leakages in the roof membrane
- For non-invasive assessment of roof moisture content, thermal insulation, and other types of facades
- For locating leaks in ceilings, walls, and floors
- Quick and easy to use. Displays results immediately.
- Lightweight, easy to handle, with a comfortable telescoping handle
- The “hold” function, which freezes the measurement result on the display
- Inexpensive to purchase and operate compared to invasive methods
Measurement depth
Depending on the density of the material being tested, the signal emitted by the electrodes can penetrate to a maximum depth of approximately 10 cm.
It is recommended that the thickness of the material being tested be at least equal to the maximum penetration depth.
