Key Features
The AccuMASTER XT (7440) is a handheld pin-type moisture meter designed to find hidden leaks and measure moisture content in wood, concrete and other building materials. It combines a large backlit LCD, easy one-hand operation and go/no-go firewood/lumber readouts so homeowners, contractors and woodworkers can quickly triage damp areas and decide whether wood is dry enough for burning or building.
Key Considerations
Measurement method: pin-type electrical resistance — requires inserting pins into the material for a localized moisture reading.
Target materials & ranges: marketed for wood, concrete and general building materials; firewood moisture ranges called out on the product page (Low 5–11%, Medium 12–15%, High 16–50%).
Display & usability: large backlit screen, hold/freezing of readings, audible/visual alerts for quick field decisions.
The AccuMASTER XT uses probe pins to measure electrical resistance between two points — a direct localized method that gives a numeric moisture value for the spot tested. That makes it reliable for confirming internal moisture in lumber, studs and firewood, but remember each test point leaves tiny pin holes in finished surfaces.
These factors represent the most critical aspects that will impact your satisfaction with this product.
Customer Reviews
Very pleased with the product would recommend.
Arrived quick, runs on 9 volt battery, you can use the 2 prong pinto test drywall humidity, or a flat scan. Great tool, handy for water/leak detection. Great value.
