Tramex Concrete Encounter CME 4 is a handheld portable electronic moisture meter operating on the principle of non-destructive impedance measurement. Parallel co-planer electrodes are mounted on the base which, during operation, transmit low-frequency signals into the concrete floor screed to a depth of approx. 12.5 mm (0.5in). While concrete under normal conditions can never be completely dry, the instrument has been calibrated on acceptably dry material. In operation it compares the change in impedance caused by the presence of dampness and displays this on a clear, easy to read analog dial.

To carry out moisture tests simply brush any dust from a smooth area of concrete and also from electrodes, switch on the concrete Encounter CME 4 firmly onto the surface, fully compressing the spring loaded signal enhacing contacts on the base of the Tramex CME 4. Read the moisture content from the clear analog dislay.

The CME 4 is calibrated to give percentage moisture content readings on a clean, bare dust free concrete floor slab, therefore readings taken on concrete slabs through paint, coating, adhesives or other materials on the surface of the slab should be regarded as qualitative or comparative and not quantitative.

Regular checking of moisture content during the drying out period of a new concrete floor or floor screed is important to ensure it has reached sufficient dryness to accept the floor covering. Excess moisture in the concrete could cause latent problems such as condensation or failure of the adhesive under the floor covering.
The Concrete Encounter 4 will give you an instant reading of moisture content up to 6% concrete; up to 0 - 10 comparative on gypsum screed enabling you to make an informed decisions on when to install the floor covering.
To use, simply switch on and hold the instrument firmly against the surface. As many non-destructive tests as you need can be carried out in seconds without the need to drill or damage the concrete.
