Gypsum Moisture Testing with Tramex Concrete Moisture Encounters - CME5 and CMEX5

Tramex Concrete Moisture Encounters for Gypsum - CME5 and CMEX5
This video explains how Tramex Concrete Moisture Encounter (CME5 and CMEX5) meters can be used to test gypsum floors to evaluate if they are dry enough for installing floor coverings.
Both CMEX5 and CME5 have gypsum scales for moisture measurement.
On the CME5, look for the yellow gypsum scale (0-10). A reading of 4 or less indicates a dry number (similar to the dry threshold for concrete).
CMEX5 offers two gypsum scales:
- Gypsum reference scale (0-12): same as CME5, 4 or less for a dry number.
- CM Anhydrite scale (0-2.7 Max): 0.5 or less indicates a dry number. Some manufacturers specify this scale, emphasizing the 0.5 for dry number.
The benefit of the Concrete Moisture Encounters is that they provide a larger testing area on the pads, and read about 3/4 inch deep, allowing a more accurate assessment of gypsum dryness for further steps.
