Our Multifunction Moisture Meter measures moisture content in wood and other building materials such as sheetrock, drywall, wallboard, concrete, mortar, plaster. It can also measure humidity, air temperature and dew point using the built-in probe. The unit allows for moisture measurement using 3 different methods - the built-in penetration pins, using the pin-less moisture sensor on the back of the unit or using the external probe which is included with the unit. Includes meter, external probe, 9v battery, instructions and hard plastic carrying case. • Quickly measures the moisture content of wood and other building materials along with temperature and humidity • Easy to read, large dual display with automatic backlight feature • Simultaneously displays moisture value of wood or material being tested, Air Temperature, Humidity • Programmable high/low moisture and humidity alarms • Built-in humidity/temperature probe measures: Relative Humidity, Air Temperature and Grains Per Pound (GPP)/(g/kg), Dew Point (DP), Vapor Pressure, and condensation point • Automatic calculation of differential Temperature (IR - DP) to determine condensation point • Min/Max and Data Hold function • Auto power off and low battery indication • Size (HxWxD): 7" x 2.75" x 1.5" • Weight: 10oz.
