The Tramex RWS Roof and Wall Scanner is a multi-mode non-invasive impedance scanner designed for the instant, precise and non-destructive evaluation of moisture conditions and leak tracing in roofing per ASTM D7954 and in wall systems of the building envelope.
The Roof & Wall Scanner detects and evaluates the moisture conditions within roofing and wall systems 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 analog 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.
The Roof Master Kit is the complete kit for the Rooﬁng Professional, allowing for continuous and point-of-contact, non-destructive surveying of moisture conditions in rooﬁng and waterprooﬁng systems, per ASTM D7954, up to 6 inches in depth, as well as non-destructive measurement of moisture conditions in concrete decks, measurement of moisture conditions in wood decks, and ambient relative humidity and dew point conditions. This kit comes in a protective heavy-duty wheeled carry case with die-cut foam lining.
The Roof Inspection Kit allows for point-of-contact, non-destructive checking of moisture conditions in rooﬁng and waterprooﬁng systems, per ASTM D7954, up to approximately 100 mm (4") in depth, as well as non-destructive measurement of moisture conditions in concrete decks, measurement of moisture conditions in wood decks, and ambient relative humidity and dew point conditions.
Instant and non-destructive moisture content tests per international standard ASTM F2659 with the CMEX II, a digital version of the CME4 handheld electronic moisture meter, designed for the instant and precise measurement of moisture content in concrete slabs, featuring Carbide Method equivalent scales for concrete and anhydrite screeds and giving comparative readings in other cementitious floor screeds.
