10 Best Infrared Moisture Meters 2026 in the United States

The FLIR MR277 Moisture Meter is a comprehensive tool designed for building inspection, combining moisture detection with thermal imaging and a hygrometer. One of the standout features is its thermal imaging technology, which offers four times the resolution of earlier models. This helps identify moisture, air leaks, and insulation voids quickly, making the inspection process more efficient.

Additionally, the integrated non-invasive sensor and external pin probe ensure accurate moisture readings, crucial for diagnosing building issues. The inclusion of thermal and visual imagery in one file, along with hygrometer readings and laser location, makes documenting problems streamlined and effective. This is particularly beneficial for professionals who need to provide detailed reports on building conditions.

The device is also backed by a 10-year warranty, reflecting its durability and build quality. However, it's relatively heavy at 2.1 pounds, which might make prolonged use a bit cumbersome. It runs on alkaline batteries, and though it includes a charger and USB cable, relying on battery power could be seen as a limitation in constant-use scenarios. Despite these minor drawbacks, the FLIR MR277 is an excellent choice for those in the building inspection industry who need a reliable, precise, and comprehensive tool.

The Tramex Concrete Moisture Encounter CMEX5 is a versatile tool designed for measuring moisture in concrete, wood, and various building materials. It offers both pin and non-destructive moisture measurement methods, alongside a built-in hygrometer for checking ambient humidity, temperature, and dew point. This combination makes it suitable for professionals who need accurate moisture readings and environmental data in one device. The device measures moisture up to about 3/4 inch deep and, with optional probes, can extend deeper into concrete or test wood moisture more precisely. Its accuracy is solid, relying on gravimetric testing as a baseline, and it includes specific scales for materials like anhydrite and gypsum, which are common in construction.

The response time is quick, providing instant readings, which is useful on job sites where time is valuable. The CMEX5 features a clear digital display and connects via Bluetooth to an app, enabling users to create moisture maps, add geotags, and time-stamped reports—helpful for thorough documentation. It runs on standard AA batteries, making it easy to power in the field, and its compact, ergonomic build offers good durability for everyday use. Calibration is straightforward, ensuring reliable measurements over time.

This meter represents a strong choice for contractors, flooring installers, and building inspectors seeking a reliable, multi-function moisture meter that supports both quick checks and detailed moisture mapping. However, it might feel somewhat complex for casual DIY users due to its multiple functions and optional probes, and deeper or highly specialized moisture testing beyond 100 mm may require other tools.

The Extech MO290 is a versatile infrared moisture meter that combines a pinless moisture detector with an IR thermometer, making it a handy tool for various applications. One of its strong points is the programmable high/low moisture and humidity alarms, which can help you quickly identify problematic areas. The device also automatically calculates the differential temperature to determine the condensation point, which is useful for preventing mold growth and structural damage. The non-contact IR thermometer has an 8:1 distance to spot ratio and a fixed emissivity of 0.95, allowing you to measure surface temperatures accurately from a distance.

The large dual display with backlight is easy to read, even in low-light conditions, which can be very convenient during inspections in dimly lit areas. Additionally, the pinless measurement capability can detect moisture up to 0.75 inches below the surface, and it includes a remote pin-type probe for more precise readings with a 3 feet cable length, giving you flexibility in measuring different materials and depths. On the downside, the MO290 could be considered slightly bulky for some users due to its 0.21-kilogram weight, and the AA battery might not last as long as rechargeable options.

The build quality seems robust, but it might not be the most durable in extremely harsh environments. For those who need reliable moisture measurements and temperature readings in one device, the Extech MO290 offers a solid option, especially for home inspectors, restoration professionals, and HVAC technicians.
