Drywall Moisture meter WM700A

Moisture meter WM700A uses a non-invasive measurement mode. It is specially designed to measure materials such as drywall, concrete, softwood and hardwood. The pinless moisture meter has a built-in high-precision electromagnetic wave sensor with a maximum measurement depth of 3/4 inches. It is most accurate for objects with a thickness greater than 20mm and an area greater than 40x40mm. The drywall moisture meter can help us find mold and spots on the wall at the first time. Frequently Asked Questions What materials can a pinless moisture meter scan accurately? Pinless meters are ideal for non-invasive measurements in drywall, concrete, plywood, and softwood. They’re not suitable for metal surfaces or very rough textures. Pin-type moisture meters provide absolute moisture content readings (%MC) by measuring electrical resistance between two probes inserted into the material. They are ideal for precise measurements in wood and other penetrable materials. Pinless moisture meters, on the other hand, give relative readings using electromagnetic sensors—useful for scanning large areas quickly without causing damage. They help detect moisture patterns but do not offer exact %MC values.
