Concrete Moisture Meter
Model Encounter CME4


For evaluation of moisture condition of concrete, gypsum cement and other slabs and screeds as per ASTM 2659.

DESCRIPTION
The Concrete Encounter CME4 is a hand-held electronic moisture meter operating on the principle of non-destructive impedance measurement. Parallel co-planar electrodes are mounted on the base which, during operation, transmit a low-frequency signal into the concrete floor to a depth of approx. 12.5mm (.5 inch).
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 analogue dial.

FEATURES
  • Instant readings
  • Non-destructive in operation
  • No need to probe or drill or mechanically damage the surface
  • Reproducible results
  • Battery operated
  • Pocket sized
  • Clear , easy to read analog dial
  • Strong, robust, electrodes and body
  • Hold reading function

OPERATING PROCEDURE

To carry out moisture tests simply brush any durst from a smooth area of concrete and also from electrodes, switch on the Concrete Encounter CME4 and place 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 a clean, bare, dust free concrete floor slab. Thus, 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.

PRODUCTS DESIGN

The concrete Encounter CME 4 is a handheld 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 deth 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.
