The Concrete Moisture Encounter CMEX5 is a Tramex moisture meter that gives instant, quantitative measurement of moisture content in concrete, using gravimetric testing as its baseline. The Concrete Moisture Encounter CMEX5 tests to a depth of approximately 20mm into the slab. Excess moisture in a concrete floor can cause coating and adhesive failure, so a reliable reading before installation helps flooring and coating professionals avoid latent moisture problems.

The Concrete Moisture Encounter CMEX5 measures moisture content for concrete over a range of 0 to 6.9 percent and provides a comparative reading of 0 to 12 for gypsum floor screed. It also gives quantitative Carbide Method equivalent readings for concrete and anhydrite/gypsum substrates and screeds, with CM equivalent ranges of 0 to 2.7 and 0 to 4.3, plus a 0 to 100 reference scale and two reference scales for comparative readings. These functions make the Concrete Moisture Encounter CMEX5 suitable for performing a concrete moisture test as per ASTM F2659. A built-in hygrometer reads relative humidity from 0 to 99 percent, and with the optional Hygro-i2 probe gives 0 to 99 percent RH at plus or minus 2 percent at 25 degrees C. With optional wood pin probes the Concrete Moisture Encounter CMEX5 also reads wood moisture from 5 to 30 percent.

The Concrete Moisture Encounter CMEX5 has an ABS body measuring 180 x 85 x 40mm, weighs 357g, runs on two AALR6 alkaline cells and has a digital display. It is used by concrete coating, wood flooring and water damage restoration professionals, and is supplied by BAMR, South Africa's authorised distributor.
