10 Best Sheetrock Moisture Meters 2025 in the United States

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 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 Extech MO265 Combo Pin/Pinless Moisture Meter offers dual functionality with both pinless and traditional pin probe measurement options. This versatility makes it suitable for measuring moisture in wood, sheetrock, and other building materials. The pinless technology allows for non-invasive testing up to 0.75 inches deep, which is beneficial for assessing moisture without damaging surfaces. For more precise contact measurement, the remote pin probe is available, giving users flexibility based on their needs.

The digital LCD readout with backlighting and tri-color LED bargraph enhances readability, even in dimly lit environments, which is crucial for accurate moisture assessment. Furthermore, the replaceable measurement electrode pins add to the device's longevity and maintainability. With a lightweight design (0.21 kilograms) and compact size (8 x 2.3 x 1.7 inches), it is portable and easy to handle during inspections. The inclusion of 2 lithium-ion batteries means it is ready to use out of the box.

However, potential drawbacks include the measurement depth of only up to 0.75 inches for pinless mode, which might be insufficient for deeper inspections. Additionally, while it provides accurate readings for surface moisture, the reliance on user interpretation of the tri-color LED bargraph could lead to subjective assessments. Despite these minor limitations, the Extech MO265 is a solid choice for professionals and DIY enthusiasts needing reliable moisture measurements in various building materials.
