10 Best Moisture Meters 2025 in the United States

The FLIR MR160 Thermal Imaging Moisture Meter offers a blend of unique features and solid performance that could be beneficial for professionals in construction, inspection, and similar fields. One of its standout features is the Infrared Guided Measurement (IGM) technology, allowing users to visually identify moisture issues through thermal imaging. This is particularly useful for quickly locating problem areas without making contact. The device supports both pin and pinless measurement methods, providing versatility for different types of materials and situations.

With a measurement accuracy of +/- 0.5%, it ensures reliable readings, and the 320 x 240 pixel 2.3-inch color display enhances readability and ease of use. The small, portable design makes it convenient to carry and use in various settings. Additionally, the FLIR MR160 is built to be durable and includes an internal rechargeable battery with USB charging, adding to its user-friendliness. The included FLIR Tools software allows for documenting and generating reports, which can be a significant advantage for professional use.

Potential drawbacks include its relatively higher price point and possibly more complex operation for beginners. It may require some time to fully utilize all features efficiently. Its weight and size, although portable, could still be a consideration for those looking for extremely compact tools. In conclusion, the FLIR MR160 is a robust and feature-rich moisture meter, particularly suited for professionals who require detailed and accurate moisture analysis combined with thermal imaging capabilities.

The Tramex Moisture Encounter MEX5 is a solid choice for those needing a versatile moisture meter, especially useful for checking moisture in wood, drywall, roofing, plaster, tile, and masonry. Its standout feature is the dual-depth penetration, allowing you to compare moisture levels near the surface and deeper inside, which helps get more accurate readings by reducing interference from surface coverings. The meter covers a good measurement depth up to 0.4 inches (9mm) and offers five different sensitivity ranges, making it adaptable to various materials.

The built-in hygrometer and infrared surface thermometer add extra value by giving you humidity and surface temperature info in one device. Plus, the Bluetooth connection to an app for iOS and Android lets you track and manage your readings easily, which is handy for professionals or anyone wanting detailed reports. The unit itself is rugged and ergonomically designed for comfortable use, built to last in different work environments. Some minor downsides include that it requires batteries, which aren’t included, so you’ll need to buy those separately. Also, while it has optional pin and relative humidity probes, these are not included by default and might be needed for more specialized uses.

If you want a reliable, easy-to-read moisture meter with good material settings and modern features like app connectivity, the Tramex MEX5 meets these needs effectively without being overly complicated.

The Klein Tools ET140 Pinless Moisture Meter is designed for non-destructive moisture detection in various building materials such as drywall, wood, and masonry. One of its main strengths lies in its pinless technology, which allows for moisture detection up to 3/4-inch deep without damaging the material. This makes it particularly useful for applications involving finished surfaces or where preservation of the material is important. The device uses Electromagnetic Field (EMF) technology, which ensures accurate and reliable readings of relative moisture content from leaks and flooding, making it a handy tool for both professionals and homeowners dealing with water damage or mold prevention.

Its calibration for drywall, masonry, hardwood, and softwood is a valuable feature, ensuring that users can rely on accurate readings specific to these materials. Additionally, the reverse-contrast display and nine LED bars make it easy to read and interpret moisture levels, even in low-light conditions. The device includes handy features like a hold function, low battery indicator, and auto-power off, contributing to user convenience and battery life. Durability is a strong point, with the meter designed to withstand a 2-meter drop, which adds to its long-term usability.

However, it's worth noting that the ET140 is calibrated specifically for certain materials, meaning it may not be accurate for other types of surfaces. It runs on a 9V battery, which is included, along with an instruction manual, making it ready to use right out of the box. For those working with drywall, wood, or masonry, this moisture meter offers a reliable, non-destructive way to measure moisture content effectively. Users needing a moisture meter for a broader range of materials might need to consider other options.
