DeFelsko Concrete Moisture Meter | Positest CMM

Concrete Moisture Meter non-destructively measures the moisture content of concrete in accordance with ASTM F2659. The PosiTest CMM Concrete Moisture Meter is the fast, non-destructive impedance meter ideal for inspectors looking to quickly evaluate the moisture condition in concrete slabs.

- Easy-to-read digital display takes the guesswork out of analog scales
- Storage of 200 readings—stored readings can be viewed or downloaded
- Innovative Hold Max and Save Mode waits for the reading to stabilize, then automatically saves it into memory
- Built-in threaded mounting point for the optional Telescopic Extender to ergonomically measure without bending or kneeling
- Weatherproof, dustproof, and water-resistant—IP65-rated enclosure

Conforms to ASTM F2659
