How it Works

Search Mode Non Invasive

Search mode is used to assess the moisture level beneath the surface of solid walls and floors independently of the surface conditions. When held against the surface, the instrument transmits a signal into the material. The relative moisture level is shown on the digital display instantly. The measurement presentaion helps the user to:

  • Look for moisture behind ceramic tile, water stains, tile and vinyl floor coverings, wood, drywall, gyprock, plaster, masonry, concrete and concrete block
  • Assess, in relative terms, if the material is dry, borderline or damp condition and map the problem numerically
  • Non-invasive pinless radio frequency (RF) finds moisture from up to 120mm below the surface
  • This mode of measurement is not adversely affected by the presence of surface moisture

Note: Metal additives in concrete or foil linings can create false positive readings
