Moisture meters measure the percentage of water in materials. The technology used in them to locate water damage in buildings has advanced significantly over the last several years. The meters are not only used in building investigations, but also to determine if building materials are dry enough to be used in construction in the first place.

Today there are many specialized moisture meters on the market. There are even ASTM Standards for measuring relative humidity in concrete to determine if a concrete slab is dry enough to have flooring applied over it.

The two major types of meters, pin and pin-less (non-invasive), each have their own set of advantages. Meters utilizing pins operate on the principle of electrical conductivity. The actual pins on the meter penetrate the material being tested and the electrical resistance, which is influenced by any moisture, is registered. Pin-less meters use capacitance technology to register any moisture. A sensor pad touches the material and a radio signal is sent into the area to be tested.

As technologies advance and prices remain competitive, an ever increasing number of home inspectors, environmental investigators and building science professionals have become specialized in utilizing these tools. EMSL Analytical, one of the largest environmental testing laboratories and environmental equipment providers, has been providing professionals with moisture meters for many years.

“Choosing the right moisture meter for a specific application is essential in conducting a proper moisture investigation,” reported Jody Thomason, Director of Products Division for EMSL Analytical. “In many circumstances it can be advantageous to have both a pin and pin-less meter available to perform a complete moisture investigation,” Thomason continued.
