Klein Tools ET140 Pinless Moisture Meter for Non-Destructive Moisture Detection in Drywall, Wood, and Masonry; Detects up to 3/4-Inch Below Surface

Very useful and work perfectly

Great product and works as expected, already identified issues I was already concerned about

After dealing with a suspicious damp spot near our bathroom wall, I picked up the Klein Tools ET140 and I'm genuinely impressed. This pinless meter scans up to 3/4 inch below the surface without poking holes in your drywall, which was exactly what I needed to track down a slow leak without causing more damage in the process.Setup took maybe two minutes — power it on, select your material type, and start scanning. The readings were consistent and repeatable, which gave me real confidence I was getting accurate data rather than random numbers. I was able to map out the moisture boundary around the affected area and confirm when it had fully dried after repairs, which was incredibly useful.At $49.97, this feels like a genuinely fair price for a Klein Tools product. The build quality is solid, the interface is straightforward, and it performed reliably every time. Whether you're a homeowner doing preventive checks or dealing with active water damage, this meter earns its place in the toolkit. No complaints whatsoever.

Seems to be a great moisture meter. I believe it's accurate and the readings are consistent. Before and after planing shows a difference of .4% which proves this meter was worth the money. It also works great for other materials. Would recommend.

As a plumber, this moisture meter paid for itself on the first job. I was able to quickly locate a hidden leak behind drywall without causing unnecessary damage, which saved both time and money. The pinless design is easy to use and provides fast, reliable readings on different surfaces. Klein Tools delivered another quality product that I now keep in my toolbox at all times.

É muito bom, conferido com o detetor de umidade da Flir e ele fez a mesma detecção. Esses tipos de medidores não marcam a umidade absoluta e sim a umidade relativa, é necessário fazer o mapa de detecção. O aparelho tem um ótimo custo benefício, engenheiros diagnósticos podem apostar no aparelho, é durável mas, não tem assistência no Brasil, se quebrar, compra outro. Eu recomendo e uso.
