Tramex CME4 Concrete Moisture Encounter
A handheld electronic moisture meter used for testing moisture conditions in concrete and other floor slabs and screeds. Versatile, precise and easy to use, the Tramex CME4 allows the user to make multiple tests over a large area in the shortest possible time.
The CME4 Concrete 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 CME4 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 analogue dial.
HOW IT WORKS
To carry out tests simply brush any dust from a smooth area of concrete and also from the electrodes, switch on the Concrete Encounter CME4 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 CME4 is calibrated to give percentage moisture content readings on clean, bare dust free concrete ﬂoor slabs, with a depth of penetration of approx. 20 mm (¾”). 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.
