INTRODUCTION
Thank you for purchasing General Tools & Instruments' MMD7NP Pinless LCD
Moisture Meter with Tricolor Bar Graph. Please read this user's manual carefully
and thoroughly before using the instrument.
The MMD7NP is designed for use in woodworking, water damage restoration,
building construction and home renovation. Examples include:
• Checking for moisture on or below the surface of carpets and subflooring
• Measuring the moisture content of wood, drywall or masonry before
painting, wallpapering, sealing or treating
• Locating water leaks above ceilings, below floors or behind walls
• Selecting dry lumber
The meter is a non-invasive (pinless) instrument that can detect moisture up to
3/4 in. (19mm) below the surface of the following materials: wallboard,
masonry, hardwood and softwood. It infers the level of moisture from the
material's capacitance, which the meter measures by gauging its effect on an
electric field that the meter generates each time it is powered on.
