The MMH800 4-in-1 Pin/Pinless Moisture Meter with temperature and humidity is designed for use in woodworking, water damage restoration, building construction, and home renovation. Some examples include:

  • Checking for moisture on or below the surface of carpets
  • Measuring the surface moisture and/or moisture content of wood, drywall, or concrete before painting, wallpapering, sealing, or treating
  • Locating water leaks in roofs, floors, and walls
  • Selecting dry lumber

Because it can measure ambient temperature and humidity in addition to moisture level, the MMH800 Moisture Meter is particularly suitable for water damage restoration projects. It measures 1) temperature; 2) relative humidity; 3) moisture level using a pin sensor, and 4) moisture level using a pad sensor. The meter has both kinds of sensors, with a pair of pins on top and a split metal pad on the back.
