Why customers choose TaskHolt Tools

Overview

The General Tools MMD7NP Digital Moisture Meter offers pinless, non-invasive testing to help you spot damp areas before they become noticeable problems. Built for wood, walls, and masonry, it delivers quick readings, colored indicators, and clear feedback that fits into everyday projects around the home or workshop.

What it measures and how it helps

This meter checks moisture near the surface and just beneath, with a reading depth up to 3/4 inch (19 mm). Material ranges include softwood from 0 to 53 percent and hardwood from 0 to 35 percent, with relative readings for drywall and masonry. Seeing moisture levels at a glance allows you to decide if remediation steps are needed and where to focus effort.

Key design features you’ll notice

  • PINLESS TESTING: Non invasive, so walls and surfaces stay unmarred while you test.
  • CLEAR DISPLAY: A 2 inch diagonal backlit LCD makes readings easy to read in different lighting.
  • INDICATOR FEEDBACK: A 3 color LED bar graph, plus an audible alert, gives quick status cues.
  • HOLD AND POWER: Freeze a reading with the hold button, and rely on auto power-off and a low battery indicator for convenience.
  • ERGONOMIC DESIGN: A sturdy, ergonomic shape with rubber side grips helps you test multiple spots comfortably.

Where you’ll use it

Ideal for kitchens, bathrooms, basements, crawl spaces, attics, and around sinks or plumbing where hidden moisture might exist. It helps DIYers, tradespeople, and homeowners keep an eye on moisture trends as part of routine maintenance and follow-up checks after upgrades.

Why choose General Tools

General Tools has a long history of crafting precision tools that balance reliability with practicality. This moisture meter is meant to be a dependable companion for everyday projects, not a guarantee of outcomes. Use it as part of a broader moisture awareness plan.
