The General Tools MMH800 4-in-1 Pin/Pad RH Moisture Meter is ideal for locating water leaks and measuring moisture content of wood, drywall, plaster walls, carpeting, flooring, brick, grout, soil, paper or powders. High levels of moisture that go untreated are the main cause for harmful mold growth in the home. This tool features both pin-type and pinless (flat pad) surface sensors. With the MMH800 combo moisture meter, scanning large areas of drywall and wood is easy with the pinless pad sensor. Once moisture patches are detected, flip open the cap to expose the pin sensors for more exact moisture content readings. It features two displays; one for moisture content and one for ambient temperature and humidity. The unit provides a moisture level range of 5-percent to 50-percent in wood and 1.5-percent to 33-percent in building materials, and offers an audible indication of moisture level and storage of moisture level readings. It holds moisture level readings for convenient viewing later. The tool also has an auto diagnostic check and auto power off. Powered by a 9 volt battery (included). The unit also comes with a lanyard, 2 sets of spare pins and a user's manual.
