The MMD7NP Pinless Moisture Meter is your first step in mold prevention. Water and moisture build up in a home can lead to hazardous and unsafe living conditions. By checking suspicious water stains around the house, you can determine whether the area is wet (a perfect breeding ground for mold) or has long since dried. The MMD7NP non-invasive, non-marring moister tester detects potential moisture problems without making pinholes. Its pinless design (using a 1 x 1 pinless pad sensor) is ideal for woodworking, flooring and other applications where it is important to not damage the wood or finished surface. This water leak detector also is helpful for water damage tracing, new home inspections and home restorations where large areas need to be scanned quickly and without harming the wall or floor surfaces. It also ensures the appropriate level of surface dryness before painting, sealing or treating wood or drywall. The moisture meter is easy to use: simply slide the pad sensor over the surface of what you are measuring in order to get a read-out. Overall measurement range of 0 to 53% for softwood, 0 to 35% for hardwood and relative readings for wallboard and masonry. The backlit, large, easy-to-read digits and clearly-designed LED alerts tell you immediately if the moisture content is high, medium or low. Plus, the moisture meter has audible out-of-range alarm so you will be able to hear a high moisture alert (17% for wood, 70% for drywall and masonry) even if you are in a dark or awkward space where you can see the screen. The sturdy, ergonomic shape and rubber side grips allow for comfort even when using for multiple measurements. Every moisture meter also feature a hold function to freeze a reading to read later, auto power off and a low battery indicator. A 9V battery is included in every package.

• DETECT MOISTURE- Determine the moisture content of softwood, hardwood and other building materials (like drywall and masonry) or check water damaged areas to see if moisture is still present
• PROTECT YOUR WORK SURFACES: There are no pins on this tool, so your walls and projects can be saved from pinholes, scuffing and scratching to figure out their moisture levels
• VISUAL AUDIBLE ALERTS: If you're looking for the source of a leak behind your work surfaces, listen for the high pitch tones to give you an accurate read on where moisture is most concentrated or quickly see using the tricolor LED moisture indicator
• DEEP READS: Even without pins, this tool can read the moisture levels up to a 3/4 inch deep into the surface with an overall measurement range of 0 to 53% for softwood, 0 to 35% for hardwood and relative readings for wallboard and masonry
• EASY TO READ AND USE- Auto-calibrating, 2-inch diagonal backlit LCD screen and a 3-color LED bar graph, HOLD button, auto power-off function, out of range alarm and low battery, 9V battery included
