10 Best Sheetrock Moisture Meters 2025 in the United States

The Tramex Roof & Wall Moisture Scanner (RWS) is a pinless moisture meter designed to detect moisture in roofing and wall systems without causing damage. It works well for inspecting roof insulation, exterior finishing systems, and foam insulation, measuring moisture up to about 4 inches deep. This deeper scanning ability is helpful for finding hidden leaks and damp spots in various wall types and roofing layers.

It offers a moisture reading on a relative scale from 0 to 100, which helps pinpoint problem areas rather than giving precise moisture percentages. The analog display gives instant results, making it easy to use on-site. A nice feature is its telescopic handle, which makes scanning roofs more convenient. It runs on a single 9V battery included in the package.

The meter’s readings are relative, so it may require some experience or comparison tests to interpret results accurately. The device is a bit bulky at 4 pounds, which could be tiring for extended use. With a solid 4.5-star rating from users, it is reliable for professional contractors or serious DIYers focused on roofing and wall moisture issues, especially where non-destructive testing is preferred. It might be less suitable if you need pinpoint precision or very quick digital readouts.

The Protimeter SurveyMaster BLD5375 is a versatile moisture meter well suited for professionals needing reliable moisture measurement in drywall, wood, concrete, and more. Its dual-function design allows you to switch effortlessly between pin mode, which measures moisture inside materials, and non-invasive mode that scans surfaces without damage—great for checking sheetrock moisture without puncturing the wall. It offers accurate readings supported by automatic calibration and regular firmware updates, so you can trust the results over time. The larger, clear display improves readability on job sites, and the extended battery life means less downtime.

Bluetooth connectivity is a handy addition for saving and organizing readings with date and time stamps via a smartphone app, simplifying record keeping. User-friendly controls let you tailor features like auto shut-off and backlight to your preference, making it comfortable to use throughout the day. While it excels in advanced features, the price might be higher than basic meters aimed at casual users, and some may find the Bluetooth functions unnecessary if they prefer manual record keeping.

This moisture meter represents a robust choice for contractors, inspectors, or serious DIYers focused on precise moisture assessment in drywall and other materials.

The Protimeter BLD9800-C MMS3 is a versatile moisture meter designed for professionals who need to measure moisture in a variety of building materials, including wood, drywall, concrete, and masonry. It uses both pin mode (which involves direct contact with the material) and a non-invasive search mode, allowing you to detect moisture behind surfaces like tile and vinyl without damaging them. This dual approach makes it especially useful for thorough moisture inspections and drying monitoring.

The meter also includes a hygrometry feature to check indoor humidity levels, helping identify ventilation issues affecting moisture buildup. It comes with helpful extras like a heavy-duty probe, a calibration device, software, and a sturdy hard case, making it a complete kit for job sites. It weighs about 6.6 pounds and requires two AA batteries, which might be a bit bulky and less convenient for casual or very frequent handheld use.

This meter is suited for contractors, building inspectors, and serious DIYers who need a professional-grade tool to assess moisture issues in various construction materials with both invasive and non-invasive options.
