Unlock Hidden Moisture: Klein Tools ET140 Review for Homeowners and Pros
When it comes to detecting moisture in your home or on the job site, accuracy and ease of use are paramount. The Klein Tools ET140 Pinless Moisture Meter offers a non-destructive solution for uncovering hidden moisture up to 3/4 inch below the surface, making it an essential tool for homeowners, contractors, and professionals alike. Whether you're dealing with drywall, wood, or masonry, this moisture meter delivers fast, reliable readings without damaging the materials being tested.

Key Features
The Klein Tools ET140 is designed with functionality and user-friendliness in mind. Here’s what sets it apart:

- Pinless, Non-Destructive Moisture Detection: Unlike traditional moisture meters that require pin insertion, the ET140 utilizes advanced sensors to measure moisture content beneath the surface without leaving any marks or holes. This feature is especially valuable when assessing finished drywall, hardwood floors, or masonry without causing damage.
- Reads Up to 3/4 Inch Below Surface: With its ability to detect moisture up to 19 mm deep, this meter offers deeper insight than many pinless models that only scan surface-level moisture. This depth detection helps identify issues hidden beneath paint, wallpaper, or other finishes.
- Material-Specific Modes: The ET140 lets users easily toggle between different material modes — drywall, masonry, hardwood, and softwood — to deliver more accurate readings tailored to the specific surface being tested.
- Bright, Reverse-Contrast Display: The easy-to-read screen features a bright display with reverse contrast, which ensures visibility in low-light conditions or indoors. Additionally, an LED bar graph supplements the numeric values so you can quickly gauge moisture levels at a glance.
- Durability and Reliability from a Trusted Brand: Backed by Klein Tools’ legacy of quality and precision craftsmanship dating back over 160 years, the ET140 brings professional-grade reliability to every job without breaking the bank.
