Tramex Concrete Moisture Encounter CMEX5 | Meter for Measuring Moisture Content & Relative Humidity in Concrete, Wood & Building Materials
Most important from
21 reviews
The Tramex Concrete Moisture Encounter CMEX5 is a versatile, non-destructive moisture meter designed to measure moisture content in concrete, wood, drywall, and other building materials. It offers both pin and pinless measurement options, plus a built-in hygrometer to test relative humidity, temperature, and dew point, which is useful for getting a fuller picture of moisture conditions in your environment. The meter can accurately measure moisture up to about 3/4 inch deep with its pinless mode, and with an optional external probe, it can reach even deeper into concrete slabs (up to 100 mm). Its accuracy is based on gravimetric testing standards, which is reliable for professional use.
The display is digital and connected to an app via Bluetooth, allowing you to create moisture maps and store detailed reports with timestamps and geotags, a handy feature for tracking moisture over time or sharing results with contractors. The device requires two AA batteries and might be a bit heavier and bulkier than simpler handheld moisture meters. It is more expensive than basic models and may offer more features than a typical homeowner needs.
This meter is well-suited for professionals or serious DIYers who want detailed, precise moisture data for sheetrock and other materials, especially when working with concrete floors or slabs. For those needing a reliable tool that combines moisture content and humidity readings with advanced reporting, the CMEX5 is a solid choice. However, if you only require simple moisture checks without the advanced features, lighter and more affordable options are available.

Tramex Roof & Wall Moisture Scanner RWS | Pinless Meter for Measuring Moisture Conditions in Walls & Roofing Systems
Most important from
13 reviews
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 General Tools MMD7NP is a pinless, non-invasive digital moisture meter designed to detect moisture levels in materials like wood, drywall, and masonry without damaging the surface. It measures moisture up to about 3/4 inch deep, making it well-suited for checking sheetrock and other wall surfaces.

Its backlit 2-inch LCD screen, combined with a 3-color LED bar graph and audible alerts, makes readings easy to see and understand in various lighting conditions.
Additional features like auto-calibration, a hold button, and alerts for low battery or out-of-range readings improve usability and convenience.

Users focused on preventing mold or water damage in homes will find this meter particularly helpful for early detection. The device does not connect to any smart home systems and is powered by a 9V battery, which is standard but may require replacement over time.
