What is a Moisture Meter and How Does it Work?

A moisture meter, also known as a damp meter or moisture tester, is a handy tool used to measure the level of moisture in various materials such as wood, drywall, and concrete. It works by utilizing an electrical circuit that measures the conductivity between two metal probes. When the probes come into contact with a conductive material, such as damp wood or wet drywall, the electrical current will pass through the material, giving a reading of the moisture content.

Moisture meters come in different types and can be used for various purposes. There are pin-type moisture meters that use two long pins to penetrate into the material being tested to read the moisture level. There are also pinless moisture meters that use radio frequency signals to measure the amount of moisture within an inch below the surface of non-conductive materials such as concrete or drywall. Other types include combination meters that have both pinless and pin-type capabilities. However, regardless of their type, all moisture meters can be used on walls to detect any hidden moisture issues.
