Multi-mode moisture scanner for
non-destructive moisture detection and
leak tracing in the building envelope including:
• Built-Up
• Non-Conductive Single Ply
• Modified and Foamed
Roofing Systems
• Exterior Insulation and
Finishing Systems
(EIFS).
The RWS
incorporates two of
Tramex’s well-known
moisture scanners, the
Leak Seeker for
Roofing, and the
Wet Wall Detector for
EIFS, incorporating all the
benefits and features of
both these time proven
instruments into this one
instrument.
The Tramex 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 designed and manufactured by Tramex who have
been producing a range of moisture detection and scanning
instruments since 1980.
The Tramex RWS
For non-destructive moisture evaluation of Roofs and EIFS Building Envelope.
For tracing leaks into the waterproofing membrane back to the source.
Fast and easy to operate.
Instant clear readings.
“Hold” function facilitates ease of recording readings.
Lightweight hand held and battery operated.
Inexpensive to purchase and operate when compared with other non-destructive
testing methods.
The Problems of Excess Moisture in the Building Envelope.
By visual inspection, the location of excess moisture and decay in or behind EIFS or Roofing Systems can be difficult
and near impossible, 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.
How does the RWS Detector Work?
The Tramex 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.
The Fast Non-Destructive Way to Detect Excess Moisture.
For EIFS, the Tramex RWS has been especially developed to aid in the detection, location and tracing of excess mois-
ture 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.
