Concrete Moisture Meter Design
The Tramex Concrete Moisture Encounter CME5 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 Tramex CME5 concrete moisture meter 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.
Concrete Moisture Meter - Operating procedure
To carry out tests simply brush any dust from a smooth area of concrete and also from the electrodes, switch on the CME5 concrete moisture meter 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 Tramex Concrete Moisture Encounter CME5 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.
