Moisture Meter MMD950 - Humidity Sensor for General Use

The General Tools Moisture Meter MMD950 is a reliable and accurate tool for detecting water build-up. This tester can be used on wood, drywall, and concrete, featuring two measurement modes. It can detect low, medium, and high damp tones, with green, yellow, and red LED visual alerts, as well as an audible out-of-range alarm to alert you to high mildew levels.

The MMD950 has a sturdy, ergonomic shape with rubber side grips for comfortable use at various angles. The protective cover doubles as a calibration checker and provides a spare pin compartment. The monitor includes a hold function to freeze a reading and has an auto power-off with an adjustable trigger. It comes with a custom hard plastic carrying case, and replacement pins are available.

This precision specialty instrument is commonly used by contractors, woodworkers, and homeowners to detect moisture and water damage under tiling, locate moisture in sub-floors beneath carpeting and wood flooring, and check moisture in masonry. The two different modes allow users to measure moisture in hard-to-reach areas, narrow spaces, and uneven surfaces. The spherical sensor measures the average moisture level up to a depth of 4 inches, providing superb repeatability.

The MMD950 can be used as a leak detector to check for moisture on or below the surface of carpets, ceilings, and sub-floors. It features an auto power-off after 3, 5, or 10 minutes, making it a convenient tool for various projects. The dual displays, including a jumbo LCD and a 40-dot tri-color LED bar graph, offer two measurement modes: pin (%WME) and pinless (REL). It includes a 9V battery, a remote pin-type probe, manual/auto-calibration, and a hold function.

For an accurate reading in pin mode, users can use the attached pins or the 46-inch cable with pins, inserting them into the surface material. The pinless sensor on the back can detect water leaks up to 4 inches behind walls and ceramic tile, enabling early prevention of mold formation.
