10 Best Pinless Moisture Meters 2025 in the United States

The FLIR MR77 is a pinless moisture meter designed to provide quick, non-invasive moisture readings, which is great if you want to avoid damaging surfaces. It’s easy to use and comes with a fresh pH buffer for calibration, along with a helpful temperature vs. pH reference table—this shows FLIR's attention to accuracy and consistency. The included rinsing solution and pouch help keep the sensor clean, which is important for reliable measurements from different materials.

The device is moderately sized and lightweight, making it portable. It runs on a lithium-ion battery that’s included and has a sturdy build backed by a limited lifetime warranty, suggesting good durability. Since it's a tabletop model, it might be better suited for controlled environments rather than handheld fieldwork.

The FLIR MR77 appears user-friendly and durable with thoughtful calibration aids, though the specifics on moisture measurement capabilities are not highlighted.

The Protimeter SurveyMaster Dual-Function Moisture Meter is a versatile tool that combines both pin and pinless moisture measurement, making it well suited for users who need flexibility in checking moisture in materials like wood, drywall, concrete, and even fiberglass boat hulls. It offers a solid measurement range and accuracy, enhanced by automatic calibration features that help maintain consistent reliability over time. The device’s larger, clear display and customizable settings (like backlight and buzzer) improve readability and user experience in different environments.

Bluetooth connectivity is a strong plus, allowing you to save and manage readings easily via the Protimeter Connect app, which is handy for professionals who track multiple measurements. Battery life is notably longer than previous models, ensuring you can work for extended periods without frequent replacements. Although it includes a comprehensive kit with a protective case and calibration charts, the meter weighs about 1.3 pounds and measures 9x6x3 inches, which is fairly standard but might be a bit bulky for some users wanting lightweight tools.

The price and best seller rank suggest it’s a reliable choice but not the top-selling model in its category, possibly due to the higher cost or complexity for casual users. This meter represents a strong option for professionals or serious DIYers who value accuracy, dual measurement modes, and modern connectivity features, while those looking for a simpler, lighter, or more budget-friendly pinless meter might find other models more suitable.

The FLIR MR160 is a versatile moisture meter that combines pinless and pin-based measurement methods, making it handy for both quick surface checks and more direct moisture readings. Its standout feature is the built-in thermal imager with infrared guided measurement, which helps visually spot moisture problems before confirming them with the meter’s sensors. This can save time when inspecting walls, floors, or insulation. The measurement accuracy is good at ±0.5%, providing reliable results for most home or professional uses. It includes 2-inch pins for contact testing, while the pinless mode allows non-destructive checks, useful for avoiding damage to surfaces.

The device’s 2.3-inch color display is clear and shows both thermal images and moisture readings together, making it easier to understand what you’re seeing. It also comes with a rechargeable lithium-ion battery and a compact, rugged design, so it’s portable and durable enough for job sites. The inclusion of software to review images and generate reports is a bonus for documentation, although it may require some learning to use effectively. The MR160 carries a limited 10-year warranty, which is reassuring for long-term use.

This meter is well suited for homeowners, inspectors, and contractors who want a reliable tool that combines visual thermal spotting with moisture measurement in one device.
