10 Best Infrared Moisture Meters 2025 in the United States

The Tramex Roof & Wall Moisture Scanner (RWS) is designed mainly for professionals needing to detect moisture in roofing materials and wall insulation without damaging surfaces. Its pinless technology allows for quick scanning up to 4 inches deep, suitable for various roofing types and insulation materials. The multi-mode function lets you adjust sensitivity and depth, helping locate exact moisture sources, which is beneficial for pinpointing leaks.

It displays moisture content on a relative scale from 0 to 100, making it straightforward for practical use. The device is handheld, sturdy, and comes with a telescopic handle for roof access, making it user-friendly and durable for fieldwork. The analog reading provides instant feedback, though some users might expect a digital display for easier reading. Connectivity is limited to Wi-Fi.

Weighing 4 pounds, it is portable but slightly heavier than some competitors. This model represents a solid choice for building inspectors, roofers, or contractors who need a reliable, easy-to-use tool for identifying moisture issues in walls and roofs without causing damage. Those requiring very high precision or comprehensive digital data management might want to consider other options.

The Tramex Moisture Encounter ME5 is a handy pinless moisture meter designed to detect moisture in wood, drywall, and various building materials without causing damage. Its dual-depth measurement is a strong point, allowing users to check moisture at both shallow and deeper levels, which is useful for understanding the condition beneath surface coverings. The meter measures wood moisture content in a practical range from 5% to 30%, and it also offers a comparative scale for other materials, helping users adapt the readings to different building types. It comes pre-calibrated for common material densities, which means you can trust its measurements without needing complicated setup. The large analog display and an optional audio warning make it easy to notice high moisture levels quickly.

Adding to its convenience, the ME5 supports Bluetooth connectivity with an app that helps create moisture maps and reports with geotagging and timestamps—ideal for professionals who need to document their findings. The build is durable and ergonomic, making it comfortable to hold and use on-site. On the downside, while the device is precise for everyday needs, it may not offer the highest resolution or fastest response time compared to more advanced models, which could be a limitation for very detailed or rapid testing scenarios. Also, it relies on AA batteries, so users should keep spares on hand.

The Tramex ME5 is well-suited for homeowners, contractors, and inspectors looking for a reliable, easy-to-use moisture meter that balances accuracy with useful features and portability.

The FLIR MR77 Pinless Moisture Meter offers a variety of features that make it useful for those needing to measure moisture levels accurately and efficiently. One of the key strengths of this device is its ease of use. It comes with a convenient pouch for storage, reducing the need for a separate container for calibration fluids. Speaking of calibration, the device includes fresh pH buffers and a helpful table indicating the pH value relative to temperature, making precise calibration straightforward. The rinsing solution provided helps keep the pH electrode clean between measurements, which is crucial for maintaining accuracy and preventing contamination.

The device also boasts a limited lifetime warranty, offering peace of mind for long-term use. While the product is fairly lightweight and compact, making it easy to handle, there are some drawbacks. The product dimensions (6.3 x 3 x 8 inches) and weight (0.29 kilograms) suggest it might not be the most portable option compared to more compact models. Additionally, the reliance on a single lithium-ion battery, though included, may be a point of concern for those who prefer devices with rechargeable or more commonly available battery types.

The FLIR MR77 appears to be a solid choice for general moisture measurements, particularly for users who value ease of use and accurate calibration features.
