MT35 Technical Specifications
Can this meter detect moisture inside walls?
Yes. This pinless moisture meter features a max detection depth up to 19mm. It needs no drilling and can detect hidden moisture inside walls without damaging the wall surface.
What drywall reading indicates risky moisture level?
For drywall:
0.1%~1.4% = Dry & safe
1.5%~2.9% = Moist, needs attention
3% and above = Wet & risky, high chance of mold, peeling and hollow wall.
Is it suitable for home inspection and construction testing?
Ideal for home inspection, renovation, and construction. Features 6 professional modes for wood, drywall, plaster, screed, and concrete. Non-destructive with LED, buzzer, and adjustable threshold.
How to find water leak locations?
Take multi-point readings along walls, floors, corners, avoid metal. Compare relative values: if any point reads much higher than nearby areas, reaches WET zone, and triggers red light & buzzer, it is a suspected leak or moisture source.
Can it detect moisture behind tiles?
yes. The depth of the moisture meter is 19mm, and you can use a mortar layer or concrete mode to measure the moisture behind the tiles without damage. Avoid nearby metal interference and test several points to obtain accurate results.
