You can always rely on our General Tools LCD Moisture Meter MM8 to give you the most accurate readings when measuring the moisture content in your basement, bathroom walls, and roof. Stop water damage and mold formation before it becomes problematic. Our tool features a hi-visibility white on black screen with LCD digits for easy readability from any angle. It also features an ergonomic construction and includes non-invasive sensing technology so that it won't scratch or mar the surface material. This handy device has separate out-of-range alarms for wood and building materials, and our humidity tester has colored green, yellow, and red LED visual alerts. It also features a hold function that freezes the reading so you can view it later. General Tools has been a recognized leader in the innovation, design, and development of specialized home inspector tools for many years. We encourage craftspeople, artisans, and DIYers to work smarter, measure better, and increase productivity.
