Tramex · Tramex Moisture Encounter ME5 | Pinless Meter for Measuring Moisture Content in Wood, Drywall & Building Materials
View on AmazonPrice and availability are shown on Amazon and can change at any time.
The Tramex ME5 is a pinless moisture meter with a dual-depth mode that reads at up to 9 mm (0.4 in) and up to 30 mm (1.25 in). That depth control is the feature that matters most: it lets you separate surface moisture from core moisture and reduce the influence of coverings. The listing states a wood moisture range of 5 to 30 percent and a 0 to 100 comparative scale for other materials. It does not publish accuracy figures or resolution, so treat the readings as relative indicators rather than laboratory measurements. If you need to compare moisture at different depths without making holes, the ME5 is built for that. If you need absolute percent moisture content in materials other than wood, the listing does not provide it.
The one specification that decides if the ME5 suits your job
The ME5’s dual-depth measurement is the specification to check first. The listing states a shallow depth of up to 0.4 inches (9 mm) and a deep depth of up to 1.25 inches (30 mm). In practice, that means you can take a reading that is dominated by the surface layer and another that reaches further into the material. For a tiled floor or a membrane-covered roof, the shallow setting helps you judge the covering itself, while the deep setting helps you see whether moisture is present in the substrate beneath. Without that depth control, a pinless meter gives you one blended reading and you have to guess where the moisture sits.
If your work involves comparing surface and core moisture, or eliminating the influence of a covering when testing what is underneath, this feature is the reason to choose the ME5. If you only ever need a single reading of the top few millimetres, a simpler pinless meter may be enough. The listing does not state whether the depth setting is adjustable in steps or simply a two-position switch; it describes shallow and deep penetration only.
What the ME5 measures and how it reports it
The ME5 is a pinless, non-destructive meter. It does not drive pins into the material, so you can take repeated readings without leaving holes. The listing states that it measures wood moisture content from 5 to 30 percent. For other materials, it provides a 0 to 100 comparative scale. That comparative scale is not a percent moisture content; it is a relative index that helps you compare one spot with another or track drying over time. The listing also mentions adjustment tables for wood type density, which matter because pinless meters are sensitive to density and species.
The display is analogue, and the listing mentions an optional high moisture audio warning tone. That tone is useful when you are working in a roof space or behind furniture and cannot watch the needle continuously. The listing does not publish accuracy figures, resolution, or the exact number of wood species in the adjustment tables. Those gaps mean you should not treat the ME5 as a calibrated instrument for absolute percent moisture content in materials other than wood. For wood, the 5 to 30 percent range is stated, but the accuracy within that range is not published.
Where the ME5 fits in a building inspection
Pinless meters are often used as a first pass in a building inspection. You scan a wall, floor, or ceiling without making holes, and you look for elevated readings that suggest moisture. The ME5’s dual-depth feature adds a second dimension: you can check whether a high reading is coming from the surface or from deeper within the assembly. That is particularly useful when a wallcovering, tile, or membrane is present, because the shallow reading can be influenced by the covering while the deep reading reaches the substrate. The listing states that the meter is pre-calibrated to various material densities, including wood, drywall, plaster, roofing, tile, masonry, walls, floor, and ceiling.
For a broader look at how pinless meters fit into inspection work, see our guide to pinless moisture meters. If your work is mostly on drywall, our drywall moisture meter guide covers the specific considerations. And if you are using thermal imaging to find suspect areas before you meter them, the article on using thermal imaging to find moisture problems explains the workflow.
The maintenance and checks the listing does not mention
The listing does not publish a calibration interval or a recommended verification method. Pinless meters can drift over time, and the reading can be affected by the material’s density, temperature, and surface contact. The listing states that the ME5 is pre-calibrated to various material densities, but it does not say how often you should check that calibration. A practical approach is to keep a reference sample of a material you know and to take a reading on it periodically. The listing also does not state whether the meter has a battery level indicator or what battery type it uses. Those are gaps you should be aware of before relying on the instrument for critical work.
The analogue display is another point to consider. Analogue needles can be easier to read when the value is fluctuating, but they do not give you a digital record. The listing mentions Bluetooth connectivity and an app for creating visual test results and maps, with geotagging and time-stamping. That app is how you capture readings for a report. The listing does not state whether the app is available for both iOS and Android, or whether the Bluetooth connection is required for basic operation. Assume that the meter works standalone, but the reporting features depend on the app.
Where the ME5 stops being the right instrument
The ME5 is a moisture meter, not a thermal camera. It tells you about moisture at the point of contact, but it does not show you a temperature pattern across a wall. If you need to scan a large area quickly to find suspect zones, a thermal camera is the better first tool. Our guide to thermal cameras for home inspection explains what to look for. The ME5 is also not a pin-type meter: it does not measure resistance between pins, and it does not give you a direct percent moisture content reading in materials other than wood. If you need that, a pin-type meter is the appropriate choice; our pin-type moisture meters guide covers them.
Finally, the ME5 is not a substitute for a laboratory test or a professional moisture assessment. The listing does not publish accuracy or resolution, so the readings are best used comparatively: to find elevated moisture, to map its extent, and to track drying. If you need to certify a building as dry, you need a calibrated instrument with published accuracy and a documented verification method.
Is the Tramex ME5 the right pinless meter for you?
The ME5 is worth considering if you need to compare surface and core moisture without making holes. The dual-depth feature is the standout specification, and the wood moisture range of 5 to 30 percent plus the 0 to 100 comparative scale covers common building materials. The listing does not publish accuracy or resolution, so the ME5 is best suited to comparative work: finding elevated moisture, mapping it, and tracking drying. If you need absolute percent moisture content in materials other than wood, or a documented calibration certificate, the listing does not provide enough information to rely on it for that purpose. For many inspection tasks, the ME5 is a capable first-pass tool, especially when paired with thermal imaging and a pin-type meter for confirmation.

Frequently Asked Questions
What is the difference between the shallow and deep depth settings on the ME5?
The listing states a shallow depth of up to 0.4 inches (9 mm) and a deep depth of up to 1.25 inches (30 mm). The shallow setting reads closer to the surface, while the deep setting reaches further into the material. That lets you compare surface moisture with core moisture and reduce the influence of a covering when testing the substrate.
Does the ME5 measure moisture content in materials other than wood?
The listing states a 0 to 100 comparative scale for other materials. That is a relative index, not a percent moisture content. The only percent moisture content range published is for wood, from 5 to 30 percent. The listing does not state absolute percent moisture content for drywall, plaster, masonry, or other materials.
Is the ME5 accurate enough for professional moisture measurement?
The listing does not publish accuracy figures or resolution. Without those, the ME5 is best used for comparative readings: to find elevated moisture, to map its extent, and to track drying over time. For certification or laboratory-grade measurements, you need an instrument with published accuracy and a documented calibration method.
Does the ME5 require a smartphone app to work?
The listing describes Bluetooth connectivity and an app for creating visual test results and maps with geotagging and time-stamping. It does not state whether the app is required for basic measurement. The meter itself has an analogue display and an optional audio warning tone, so basic readings appear to work without the app. The listing does not specify which mobile platforms the app supports.
How often does the ME5 need calibration?
The listing does not state a calibration interval or a verification method. Pinless meters can drift, and readings are affected by material density and surface contact. A practical approach is to keep a reference sample and check the meter periodically. For critical work, follow the manufacturer's recommendations, which are not included in the listing.
Can the ME5 detect moisture behind tiles or roofing?
The deep depth setting reaches up to 1.25 inches (30 mm), which can help you assess moisture in the substrate beneath a covering. However, the reading is influenced by the covering material and its density. The listing states that the meter is pre-calibrated to various material densities, but it does not state how thick a covering can be before the deep reading is compromised. Use the shallow and deep readings together to build a picture.
