About this item

  • ESTIMATE MOISTURE CONTENT QUICKLY AND EASILY – detector offers ideal dual functions of pin and pinless sensors in one. Use the pinless pad as a quick “ranging” feature to scan a large area for suspect areas without leaving holes. Then, switch to pins to quantify moisture level at various depths
  • PERFECT FOR HOME INSPECTIONS – Use the pad for quick non-invasive pinless scanning to find locations with higher than average moisture behind a wall or under a floor. CAUTION: Powerful pinless pad sensor measures to ¾” but can be influenced by materials up to 2 inches below subject material (e.g., metal screws, nails, workbench supports, etc.) Keep fingers clear of pad scanning area. Use pad to detect variations from normal and use pins to quantify it.
  • CHECK LUMBER AND HARDWOOD BEFORE BUILDING AND WOODWORKING – Use the pins to know the moisture content of your wood to make sure you’re not using damp, moist wood on your projects to avoid cracks, splits, warping. Ensure wood flooring has acclimated before installing
  • EASY TO USE – Large easy-to-read backlit display. Sturdy, hand-friendly tester body feels solid when pressing replaceable pins into materials. Hold key freezes reading. Test lumber or porous building materials – drywall, carpet, brick, concrete and plaster

Product Description

The 7445 AccuMASTER Duo Pro Pin & Pinless Modisture Meter is ideal for helping you measure moisture content in hardwood, lumber, wood flooring, brick, concrete, drywall and plaster. Its dual-sensor system can help you speed up and improve your moisture detection using either its pa or pins. It’s the best of both worlds.

WOODWORKERS AND CRAFTSMEN -- can use the pins to check moisture content percentage quickly and easily before purchasing or using lumber and hardwoods.

PRO AND DIY REMODELERS & FLIPPERS -- discover hidden water damage in floors, walls and under carpets due to roof leaks, flooding, burst pipes, underground seepage or other water sources. Locating high levels of moisture content can help you know where to repair to avoid further damage and to stop toxic growths or other health risks.

YOU CAN EASILY SEE -- AccuMASTER’s large, well-designed LCD display and always-on backlight means you can easily read it in dimly lit jobsites, lumberyards, workshops, or even at your wood pile at night. Plus, the Hold function lets you freeze a reading on the display for viewing at a more convenient angle.

USER FRIENDLY, SIMPLE TO UNDERSTAND – In pin mode firmly push the (replaceable) sharp, stainless steel pins into test material. Or, in pad mode place the back of the meter on the surface you want to search for moisture. The easy-to-read digits and clearly-designed icons tell you immediately if the moisture content is high, medium or low. Plus, there are optional audible alerts so you can hear the level even if you are in a dark or awkward space where you can’t see the screen. The sturdy, hand-friendly shape and rubber side grips let you take measurements in comfort.

EVERYTHING YOU NEED TO GET TO WORK -- The sturdy AccuMASTER XT Moisture Meter offers accuracy and user-friendly features. Includes a 9-volt battery, batter-saving auto shut-off (3 mins).

Ready to use

The moisture meter comes with a protective cap, one set of stainless steel test pins, 9V battery and a user’s guide so you can start using the moisture meter right out of the box.

😎👍🏻🛥Used on boats to check moisture and worked great and very accurate
5 Stars
😎👍🏻🛥Used on boats to check moisture and worked great and very accurate
was skeptical about this moisture meter compared to all the “good Professional ones” for several hundreds of dollars but this one was used to help survey several boats along side the CT 33 moisture meter. is exactly the same readings as the Expensive analog meters and this one has prongs and plate sensors and digital. Very easy to use, insert battery, power button and pick 1 of 4 options, has visual and audible along with the hold option if you can’t see the screen while metering. This $70 saved me hundreds before hiring a boat surveyor and thousands on buying a boat with wet internal wood 👍🏻
