The RWS has dual operating modes for EIFS and Roofing. Each of these modes has 2 ranges of sensitivity for both deep and low penetration sensitivity, enabling the scanning of Roofing, and EIFS, with a signal penetration ranging from the surface up to approximately 4” (100mm).

The RWS is 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. The RWS gives vital information necessary to evaluate and carry out moisture assessment on the condition of most fiber reinforced EIFS wall cladding systems, roofing systems such as built up, non-conductive single ply, modified and foam roofing at an affordable cost and without complications.

For EIFS, the RWS has been especially developed to aid in the 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. For Roofing it will detect interply moisture, excess moisture in the insulation material, and moisture in or on non-conductive roof decks.

It is easy and fast to use, light to carry and can be operated with one hand. Having detected and located the areas of excess moisture the RWS can be of great benefit in tracing this moisture back to its point of ingress or source.
