Tramex Dec Scanner - Roofing Moisture Scanner

DEC Scanner by Tramex is a non-destructive electrical impedance moisture detector for roofing and waterproofing systems. Able to detect as little as 2% excess moisture to a depth of up to 6 inches, the DEC Scanner can moisture-scan up to 100,000 square feet per day.

Light-weight and portable, use of the DEC Scanner is easy to learn through Tramex' instruction manuals and videos; no special licenses or courses are required to operate.  Rolling over the flat roof surface, low-frequency electronic signal is generated and transmitted through the rubber electrode mat into the roof material. The return signal is measured to determine the moisture content of the material being tested, and areas of high moisture identified.

Tramex DEC Scanner features three sensitivity ranges to accommodate different types roofing materials:

  • Range 1 - most suitable for single-ply and thin roof coverings such as PVC, Hypalon, and other smooth surfaces where insulation is wet and moisture close to the surface.
  • Range 2 - most suitable for multi-ply built-up and modified systems, mineral-surfaced felts, and other smooth or gravel surfaces where insulation is less wet and moisture is below the surface.
  • Range 3 - most suitable for thicker roof coverings such as mastic asphalt, thick gravel, and stone-surfaced roofing.
