The most common cause .
The ideal reading on a drywall moisture meter varies from one material to another. Non-gypsum-based materials such as cement boards should read around 8%, while gypsum boards should read around 12%. Moisture meters are designed to measure the water content in various materials, primarily wood and drywall. They provide homeowners with a way to detect potential damage .However, to get the best testing results, it’s important to understand moisture meter readings—how they work, what impacts test results, what the different moisture reading scales mean, and how to ensure the most accurate results .In this blog post, we will delve deep into understanding how and why these false readings occur and what steps can be taken to mitigate their impact. Why False Readings Occur. 1. Surface Moisture. The presence of surface moisture is one of the most common reasons for false readings with pinless moisture meters.
This means that when we were talking about the normal readings for drywall, we assumed that your moisture meter was calibrated for drywall and had a specific reading scale for drywall. The same goes for wood, concrete, and plaster. .
pinless moisture meter false readings
So moisture content (mc), and not relative humidity? You should get a "moisture meter", and check the wood framing. The wood is hygroscopic (mc matches humidity), but should generally be about 10%.

Measuring WME: The Best Moisture Meter for Concrete & Other Construction Materials. For measuring WME with a moisture meter, there’s only one option regardless of the substance being tested. Whether you’re using a moisture meter for concrete floors or a wall’s drywall, you’ll need a pin-type moisture meter. Yes, moisture meters can give false readings when used on drywall because of metal materials such as corner beads, screws, nails, pipes, or old plaster underneath the wall’s surface. To prevent this from occurring, it’s important to ensure that any area being tested is free of these materials before taking measurements.
Drywall moisture readings over 0.5% Moisture Content should be considered higher than generally acceptable and require further drying or investigation and mitigation.
Drywall needs to be as dry as possible since moisture can negatively affect its structural integrity and may cause microbial growth.
Moisture readings in drywall can be taken with a .
Look for moisture levels that are between 5 and 12%. Use a moisture meter with a drywall or gypsum setting, or take a relative measurement using a know dry area as your baseline measurement. Replace any drywall over 17% or that has obvious stains or water damage. Further reading: Our complete review of the best moisture meters for drywall.Ideally, you’ll want a specialized device to use as a moisture detector for drywall. This is where drywall moisture meters are useful. Drywall meters, like Delmhorst’s BD-2100 and TECHCHECK PLUS, are pin moisture meters that have a special drywall scale setting designed to get accurate readings of moisture in drywall as low as 0.1% MC.So, Delmhorst’s drywall scale moisture meters can accurately detect moisture content in drywall to values as low as 0.1% or 0.2%. Drywall scale meters are often useful for the construction, home inspection, and water damage restoration industries. One surprising use for drywall scale meters is to check Gyp-Crete flooring. Since Gyp-Crete is .
pinless humidity meter false readings
Moisture meters can give false readings when used on plaster walls. This can occur if the meter is faulty or an issue with the calibration. Also, inaccuracies can arise if the wall needs to be adequately prepared before testing. To ensure accurate readings, a premium-quality moisture meter must be calibrated and tested against a known standard. Whileit is always a good practice to be cautious when a moisture meterindicates an increased level of moisture within walls, I believein the case you have described that another explanation for theincreased reading is likely. When drywall contractors applygypsum or sheet rock to interior walls they often utilize agalvanized metal corner bead to .
A moisture meter can help pinpoint wet areas. Drywall may look intact upon a visual inspection, but a moisture meter check can provide that all-important certainty. Using a moisture meter regularly to help evaluate the impact of humidity levels in the home, you can find unseen moisture or water damage before its effects are visible to the human .Moisture meters for drywall The Tramex Moisture Encounters MEX5 and ME5 are calibrated to read moisture in drywall. The MEX5 provides drywall moisture content % readings with the optional pin probes as well as comparative non-destructive readings. The ME5 converts the pinless impedance reading into a qualitative moisture content value.
Type of Moisture Meter Being Used. There are two types of moisture meters commonly available today: Pin-type and pinless moisture meters. Pin-type moisture meters use the principle of electrical resistance to measure the presence or absence of water in wood, drywall, hay, and other materials.
Not waiting long enough for the moisture meter to take a reading can give false readings. Inserting the pins of the pin-type moisture meter too deeply can damage the material being tested. By avoiding these common .Concrete should have a moisture content of 5-9%, drywall should have a moisture content of less than 15%, and carpet should have a moisture reading of 5-10%. In addition, humidity readings should be between 30-50% to be considered acceptable.

Non-invasive meters that take readings via direct contact are often impacted by condensation, meaning there’s a greater risk of false moisture meter readings in drywall.However, when he used a pinless meter (Tramex moisture encounter) he was getting high reading on many (but not all) of the exterior walls (averaging 18%, though a spot on one wall was 25%). He tried to look in the walls, but the only readily available access was through the electrical outlets, which were too small to allow for visualization.
Combination moisture meters combine pin and pinless functionality for a broader range of use. This type of moisture meter is ideal for prolific DIYers and professionals that work with many building materials.

These meters read the highest moisture found first, so if moisture is on the surface (like condensation), then the reading will not penetrate below that and may indicate to the use the wall is completely wet. It could only be temporary moisture. These meters also do not work well on tile and vinyl because of the increased conductance on the .

Today I used a newly acquired moisture meter, non invasive, to check the moisture levels since it was raining. It came back at various degrees of moisture around the exposed brick anywhere from 20% to 80/90% but dry along the replaced wall and ceiling. The brick looks and feels dry though. I read that the non invasive ones can be unreliable. When it comes to the integrity of your walls, unseen moisture can be a hidden culprit, leading to more significant problems.
