10 Best Moisture Meters 2025 in the United States

The Protimeter SurveyMaster Dual-Function Moisture Meter is a versatile tool designed for professionals and serious DIYers who need reliable moisture readings in various building materials like wood, drywall, and concrete. It offers two measurement modes: pin mode for direct contact measurements and non-invasive mode for surface scanning, making it adaptable for different tasks. Its accuracy is maintained through automatic calibration and firmware updates, helping ensure consistent results over time. The larger, easy-to-read display improves usability on site, and the long battery life means fewer interruptions during work.

Bluetooth connectivity is a standout feature, allowing users to save and track readings easily through a mobile app, which is especially handy for keeping records. Customizable settings like auto shut-off, backlight, and buzzer add to user convenience. In terms of build, it is reasonably compact and lightweight at just over a pound, with a durable case included to protect the device. One consideration is that it requires alkaline batteries, which may need replacement more often compared to rechargeable options.

If you need a moisture meter that combines thorough measurement capabilities with smart features and easy data management, this model is a strong candidate.

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 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.
