Developed to aid in the non-destructive detection, location and tracing of excess moisture within the weatherproofing coatings or coverings, and deep into the insulation and substrate to detect excess moisture in the sheathing and the wood studding of EIFS systems (Exterior Insulation and Finishing Systems). For roofing it will detect interply moisture, excess moisture in the insulation material, and moisture in or on non-conductive roof decks.

How Does the RWS Detector Work? It’s an electronic hand-held Moisture Scanner and Detector working on the principle of electrical impedance. With impedance measurement, harmless signals are transmitted from the electrodes at the base of the instrument deep into the thickness of the area under test. These signals measure the change in electrical impedance which is translated into a relative moisture content reading and instantly displayed on the clear large analog dial. Readings are instant and continuous. The RWS is also fitted with an audible device which sounds at high readings.
