The Tramex Roof & Wall Moisture Scanner is extremely easy to use and provides quick and accurate readings of moisture in roofs, walls, and EIFS (Exterior Insulation Finish Systems).
The RWS has dual operating modes for Roofing and EIFS. Each of these modes has two sensitivity ranges for both deep penetration and low penetration sensitivity enabling the user to scan EIFS and roofing with a signal penetration ranging from the surface up to approximately 100mm. The RWS non-destructively evaluates moisture and traces leaks back to the source.
As an ideal moisture meter for when you need non-destructive readings, this unit helps inspectors and contractors easily find leaks and trace them back to the source.
The unit is lightweight and includes a 9V battery and a telescopic handle.
The Tramex RWS is a multi-mode non-invasive impedance moisture scanner designed for the instant, precise and non-destructive evaluation of moisture conditions and leak tracing in the roofing and walls systems of the building envelope. The RWS is used to perform ASTM D7954.
The Problems of Excess Moisture in the Building
By visual inspection, locating excess moisture and decay in or behind EIFS or Roofing Systems can be extremely difficult as normal evidence of this moisture and decay may not be visible on either side of the wall or roof. Excess moisture can be hidden and trapped in the substrate and within the thickness of the wall or roof construction. If these conditions are allowed to continue the moisture will increase, eventually leading to rot and decay and possible failure of the system and the structure. Also wet insulation loses its thermal value, resulting in unnecessary heat loss or gain and thermal movement in the structure. Early detection of wet areas and corrective remedial action makes good economic sense.
The Roof & Wall Scanner detects and evaluates the moisture conditions within roofing and wall systems and other building materials by non-destructively measuring the electrical impedance. A low frequency electronic signal is transmitted into the material under test via the electrodes in the base of the instrument. The strength of this signal varies in proportion to the amount of moisture in the material under test. The Roof & Wall Scanner determines the strength of the current and converts this to a comparative moisture content value, displaying it on a large clear analogue dial.
Moisture detection testing can be done at the time of installation, as part of an ongoing maintenance program, or prior to reparation of damaged roofing and wall systems. The RWS is a handheld, hardwearing instrument with dual operating modes for roofing and EIFS/Foam insulation systems, each with two ranges of signal penetration. Having calibrated the RWS on a known acceptably dry area, the RWS gives instant readings for the moisture survey.
