The Tramex Moisture Encounter MEX5 (part number MEX5) is a digital, dual-depth, non-destructive moisture and humidity meter for surveying moisture and humidity conditions in building structures. Moisture trapped in or behind building materials drives decay, mould and coating or flooring failure, so a single instrument that maps moisture, measures ambient humidity and reads surface temperature lets inspectors and restoration teams diagnose a problem and confirm drying without cutting into the fabric.

The Tramex Moisture Encounter MEX5 measures moisture content in wood and drywall and gives comparative readings in roofing, plaster, tile and masonry. Non-destructive readings cover 0 to 30% MC for wood and a 0 to 100 comparative scale for building materials, with a shallow signal to around 9mm and a deep signal to around 30mm so surface and core moisture can be compared. A built-in hygrometer reports ambient conditions and psychrometric values, relative humidity reads 0 to 99%, and an integrated infrared surface thermometer adds temperature measurement. With the optional Hygro-i2 probe, humidity accuracy is plus or minus 2% at 25 degrees C across 0 to 99% RH.

Optional external probes extend the Tramex Moisture Encounter MEX5 further: in-situ RH probes give equilibrium RH readings and pin probes give 6 to approximately 50% MC on wood and 0 to 8.5% MC on drywall, along with wood moisture equivalent readings. Results appear on a 58 x 35mm digital display. The ABS-bodied unit measures 180 x 85 x 40mm, weighs 290g and runs on two AA alkaline cells. The Tramex MEX5 is supplied by BAMR, South Africa's authorised distributor.
