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

I purchased this to detect moisture inside of my home. It works great and is a simple tool for even a basic DIYer. The device is easy to read, the brightness of the display is just right...especially in dark places. The price is good, given that Klein is a very reputable brand with quality tools. I was able to scan all of my walls and detected another area of high moisture that I was unaware of....unfortunately! Definitely a useful device to see what is happening on the inside of your walls.

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.

Works as advertised. Comparing this with a pinned model (half the price) that a neighbour borrowed and never returned Pros: - Multiple modes for different materials - Easy to use - Accurate, clear readings - Pinless Cons: - Uses 9V battery - Price (even on sale)

Habe ich gekauft für mein Wohnmobil und damit Feuchtigkeit am großen Panoramafenster (Dichtung) entdeckt, von Werkstatt bestätigt. Bisschen teuer, aber wahrscheinlich seinen Preis wert.

I don't know how this tool works, but it's magic. It is very easy to use and causes no damage to the surface being tested. The hardest part of using this tool is finding a flat surface that fits the entire unit. Most of the time that's not a big deal because floors, walls, wooden boards etc. are pretty flat. My challenge was with crown mouldings. The sensor is a small patch on the back of the meter, but to get the sensor to lie flat on the wall you need the entire unit to lie flat. Fortunately this is easier to use than a stud sensor because you just need to find some orientation that gets a portion of the sensor into contact with your surface of interest. In addition, you can see the readout change as you approach the surface so you can tell how well you are doing. Measuring the moisture level of a dry area helps to determine if you are getting good enough contact to the region of interest. For my need this was much better than a pin type meter because it did not drive any holes or pinpricks into the surface of my walls. Because it causes no damage I was able to test many areas to determine what dry was before getting to the area of concern. I definitely would not have done that if it meant putting little holes into the wall.
