PosiTest CMM - Concrete Moisture Meter

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
Made in USA flag with black text below
