Whether you're a contractor, home inspector, or just trying to figure out why that corner of your basement feels damp, the Protimeter Mini is the tool you want in your pocket.

It's a compact, battery-operated digital moisture meter that uses built-in pin probes to quickly check moisture levels in all sorts of building materials—think timber, drywall, plaster, masonry, and even concrete.

The display is super simple to read thanks to a color-coded system: green means dry, yellow says borderline, and red?

Yeah, that means you've got a moisture problem.

It also gives you numeric readings as a percentage for wood (% MC) and wood moisture equivalent (WME) for other materials.

The fine-tipped pins leave almost no marks, so you can test without ruining your surfaces.

Comes with an extension probe for tight spots, a calibration checker, spare pins, a carry pouch, and a 9V battery.

Trusted by pros for over 30 years, this little guy just works.
