CMEXpert ll Concrete Moisture Meter performs direct-contact concrete surface moisture testing to ASTM F2659 and can measure up to 6.9% moisture content. It can be used with HMA-650 Hygro-i Relative Humidity Probes with an electronic interface cable for ambient measurements of relative humidity, temperature, and dew point. The cable is also included with the HM-85 kit. The unit’s relative humidity range is 0–100% non-condensing. Humidity accuracy of between 10%–90% is ±1.8% at 25°C (77°F) and ±3% above 90%.
Optional HMA-661 Calibration Check Plate verifies the proper performance of the meter when used for direct-contact surface readings. Adjustments or recalibration must be performed by the factory.
