Moisture mapping is the process of determining surface moisture over an area to detect wet and dry areas using a moisture meter. It is a non-destructive technique that can be used to identify leaks, moisture intrusion, and other problems that can lead to mold growth and other health hazards.
A variety of moisture meters are available on the market, ranging from simple pin-type meters to more sophisticated non-invasive meters.
The most accurate moisture meter for a particular application will depend on the material being tested, the thickness of the material, and the desired level of accuracy. In general, non-invasive moisture meters are more accurate than pin-type meters.
Some of the most accurate non-invasive moisture meters include:
