Pin moisture meters are often considered to be more accurate than pinless moisture meters, since they take direct readings from the material, with a small pin being inserted into the material. 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. .
A non-invasive (pinless) moisture meter will measure the subsurface moisture to a depth of 20mm. This is advised where wall, floor, and wood covering prohibit moisture readings with a pin-type instrument. The Protimeter Aquant2 will measure using radio waves, penetrating beneath the wall surface including wallpaper, paint, and even tiles. False Readings From Moisture Meters. August 01, 1997 Q: We recently purchased a moisturemeter that doesn’t use steel pins to be poked into thesurface being tested. I have noticed when using this new meter onwood-frame construction covered with gypsum board or sheet rockthat even in areas where I know there is not a moisture problem,there .As a result, the normal moisture meter reading for these materials in between 0.5% and 1%. Higher values could mean a wet or saturated material. For boundary materials, the values vary depending on the physical properties of what you are testing. As a rule of thumb, you should expect the following ranges for dry materials: .
A few things to keep in mind when using a moisture meter for drywall include: Choosing the Right Moisture Meter. The first step in using a moisture meter on drywall is picking the right moisture testing device.

Check the accuracy of a moisture meter with a known reference material to verify the . Well, a moisture meter can be wrong depending on the type of moisture meter (pin-type or pinless), the quality, and how it’s used. Even the best moisture meters can produce inaccurate readings if the meters aren’t used properly. You won’t get an accurate reading if your digital moisture meter isn’t calibrated.

The most useful types of damp meters are those that measure both the moisture content in timber. the relative .
In some meters, only a slight amount of surface moisture can significantly disrupt the moisture readings. 2. Using a meter that’s out of calibration. Using a moisture meter that’s not calibrated is like that old cliché, .Pinless Moisture meters are notorious for giving false positives. Especially on concrete slabs. Especially inexpensive ones. The moisture meter I used as a home inspector was close to 0, and it would still give me false readings on concrete.
Using a Moisture Meter on Concrete. The C555 pinless moisture meter effectively measures moisture in concrete on the top ½ inch of smooth slabs. Pin-type meters are not practical for measuring moisture in concrete because variable chemical and physical characteristics can cause false moisture readings. 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. And if one area is .300 mm and even claim to profile moisture levels at various depths. These meters detect moisture in underlying substrates like framing, but results must be treated with caution. READINGS USEFUL FOR COMPARISON ONLY Using moisture meters on materials other than exposed timber is not a reliable indication of the amount of moisture below the surface.
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 .
