Tramex RWS Roof and Wall Moisture Inspection Kit for Roofing and Building Envelope Testing (0–100 Relative Scale)

A complete kit featuring the Tramex RWS Roof and Wall Scanner (combining the Wet Wall Detector and Leak Seeker)

Non-Destructive Moisture Detection for Roofing and Walls

The Tramex Building Survey Master Kit provides a comprehensive solution for instant, non-invasive moisture assessment in walls, roofing, and other building materials. It includes the multifunctional MRH3 digital moisture meter for accurate readings in drywall, wood, plaster, brick, ceramic tiles, laminates, resilient flooring, and roofing systems.

EIFS and Wall Inspection Capabilities

The included EIFS Inspection Kit features the Tramex MRHIII moisture and humidity meter, a pin-type resistance probe, and a Hygro-i® relative humidity probe. This setup allows precise measurement of ambient humidity, temperature, and dew point, while delivering in-depth moisture readings in wall materials, sheathing, wood studding, and EIFS substrates.

Significantly enhance inspection accuracy and reporting capabilities

Instruments such as the Tramex Roof and Wall Scanner provide fast, non-destructive detection of moisture within roofing systems and EIFS structures, helping inspectors quickly identify potential leak sources and areas of water ingress. For projects requiring comprehensive roof moisture evaluation, the Tramex Roofing Inspection Kit offers an integrated solution combining scanning, relative humidity measurement, and environmental monitoring for detailed condition assessments. In addition, restoration contractors and building survey professionals may benefit from the Tramex Water Damage Restoration Inspector Kit, which enables accurate moisture measurement across a wide range of construction materials including concrete, drywall, wood, and plaster during post-water-damage inspections and remediation projects.

Industries and Advantages

This kit is ideal for building surveyors, roofing contractors, restoration professionals, and quality inspectors. Users praise its fast, accurate, and non-destructive readings, with deep penetration capabilities that outpace many competing moisture meters. It combines multiple functions in a single kit, reducing the need for separate devices and improving workflow efficiency.

Q&A

Can this kit detect moisture behind walls without drilling?

Yes, the MRH3 and RWS units provide non-invasive, deep penetration moisture detection up to 4" (100mm) behind wall surfaces.

Which materials can be tested with this kit?

It works on drywall, wood, plaster, brick, ceramic tiles, laminates, resilient flooring, and roofing materials.

Does it include humidity measurement?

Yes, the Hygro-i® probe measures 0–99% ambient relative humidity along with temperature and dew point.

What is the difference between invasive and non-invasive modes?

Non-invasive mode measures wood moisture content without penetrating the surface, while the pin-type probe allows direct, invasive measurements for greater accuracy.
