The Tramex CME 5 is the successor of the Tramex Concrete Moisture Encounter 4 non destructive moisture meter.
The Tramex Concrete Encounter 5 is a hand-held electronic moisture meter using non-destructive impedance measurement for instant humidity determination in concrete floors .
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 up to 20 mm. The results give the average moisture content to a depth of approximately 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 not quantitative.

The Tramex Concrete Moisture Encounter detects and evaluates the moisture conditions within the concrete 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 or CM Equivalent value for concrete slabs and other cementitious floor screeds, displayed on a large clear analogue dial.
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.
