The Tramex Concrete Moisture Encounter – CME5 is an instant, precise, non-destructive, analog moisture meter for measuring quantitative moisture content % in concrete floors and slabs using Gravimetric testing as a baseline. The CME5 also provides comparative readings of gypsum floor screeds as well as comparative readings of concrete as per ASTM F2659. Bluetooth connectivity to the Tramex Meters App allows for visualization of readings and data reporting to mobile devices, to GeoTag test results, create, save and share photos, reports and charts. Product Design: The Concrete Moisture Encounter detects and evaluates the moisture conditions within the slab or screed 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 present in the material. The Concrete Moisture Encounter determines the strength of the current and converts this to a moisture content value for concrete slabs and a comparative value for other cementitious floor screeds, displayed on a large clear analog dial. Operating Procedure: To carry out tests simply brush any dust from a smooth area of concrete and also from the electrodes, switch on the Concrete Moisture Encounter and place it firmly onto the surface, fully compressing the spring-loaded, signal-enhancing contacts on the base. Read the moisture content from the clear analogue dial. The Concrete Moisture Encounter is calibrated to give percentage moisture content readings on clean, bare dust free concrete floor slabs, with a depth of penetration of approx. ¾” (20 mm). Readings taken on concrete slabs through paint, coatings, adhesives or other materials on the surface should be regarded as qualitative or comparative and not quantitative.
