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).

I tested it first on several wood types, but mostly the wall board in numerous spots, consistently measured 7-9% or so (“dry” reading)
So I am confident it works more than well enough…. Yes, some had delivery problems, as many products do… many more did not
Get it and make sure you have no slow water leaks, as then comes mold…
I worry about the pins. They kept loosening as I use it. I have to be careful to keep them screwed down all the way.
I've had this meter for a year, but didn't trust it nor did I fully understand how it works.
We live 2 blocks from the SF Bay with a high water table and high relative humidity.
We're installing wood floors over concrete as well as on subfloors over crawlspace.
Since we requested full moisture tests, our floor installer came by yesterday with his high priced
meters for Concrete (both surface and drilled plugs), wood pin, and Relative humidity.
I asked him the price of one of his meters and I heard $600!!!
Checked out the concrete surface with the pad on "Bldg Materials" setting, and it was identical it his!
(HEADSUP: I was getting 10% lower concrete reading until he ground down the surface glue....
so make sure you are down on bare concrete)
Also used the pins on "Wood" setting and we both got identical 11.8% on the existing hallway red oak.
(CAVEAT: His pins were much sturdier than the Accumaster pins, and I'm sure can take much more abuse. For occasional use for me this is perfect as I'm very gentle with it and carefully insert the pins straight in with the grain. You do have to push to get them in 1/4")
This is unrelated to this meter, but I was also thrilled that our Ecobee thermostat was spot on with his
expensive Relative Humidity (RH) meter!
So, all in all I'm thrilled that I have a tool that I can trust to detect moisture problems in my home!
Do get this model with both the pins and pads as it is much more versatile and worth the modest increase
in price. Overall, it's a fantastic value with it's versatility and accuracy!
