The Tramex Concrete Encounter is a hand-held electronic moisture meter utilizes non-destructive impedance measurement for moisture determination. Parallel co-planer electrodes are mounted on the unit's base which transmit low-frequency signals into the concrete or cement floor to a depth of approx. 1/2 inch (12.5 mm). The results give the average moisture content to a depth of approximately 4 inches (100 mm) during the drying period.

While concrete under normal conditions can never be completely dry, the instrument has been calibrated on acceptably dry material. It compares the change in impedence caused by the presence of water and displays moisture content on an analog dial.

The meter is calibrated to give percentage moisture content readings on a clean, bare dust free concrete floor slab, thus 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 no quantitative.  

How it works
To carry out moisture tests simply brush any dust from a smooth area of concrete and also from electrodes

After that, switch on the Tramex Concrete Encounter 4 firmly onto the surface, fully compressing the spring loaded signal enhacing contacts on the base of the meter.

Now read the moisture content from the clear analog dial.
