Moisture Detection and Measurement

 J & M’s Thermal Image Inspections“Thermography is only 1 of the tools we use to find hidden moisture. For detailed analysis and confirmation we use moisture meters to give us the FACTS about the amount of moisture in building materials and in the atmosphere of the structure.”


Since no inspection can get the moisture percentages by looking at a wall, it is vital to utilize a moisture meter.

These photos show walls with signs of moisture intrusion.


The moisture meter confirmed the high concentration of moisture, well above normal, indicating an active leak.


Hygrometer ModeHygrometer Mode


  • Measures the relative humidity, temperature, dew point, proximity to dew point, and grains per pound (GGP).
  • All these readings are logged and used in the Moisture Mapper Reporting Software and are part of the Psychrometry calculations.

Hygrometer Mode


Pin Measure Mode

  • Uses penetrating pins to determine the moisture content of wood and the Wood Moisture Equivalent (WME) value of other building materials.



Hygrometer ModePinless Measure Mode

  • Uses non-invasive radio frequencies to detect the presence of moisture without damaging materials.


Date Logger

  • Stores up too 100 results (with a date and time stamp) for downloading to our computer systems. Allows us to keep clean records of drying conditions for insurance and customer reporting.


GE Protimeter Hammer Electrode

  • Lets us get precise moisture readings at depth within materials.
  • The hammer electrode penetrates through structural materials like sub floors and framing to a depth of 1.38” (35mm). The insulated pins determine the exact moisture content of wood or the Wood Moisture Equivalent (WME) percentage of other materials.
