The moisture readings are stated as a percentage of water in wood (% H20 WME - Percent Wood Moisture Equivalent). But a reading of 12% moisture in wood is dry, whereas 12% in brick is saturated.The home inspection blog for buyers of site-built, mobile/manufactured, and modular .
Pinless moisture meters are sensitive to metallic objects, such as nails, screws, or metal brackets, embedded within the material being tested. If the device’s scanning pad comes into .
As non-invasive meters are testing for moisture presence -- the extent of which can later be confirmed by pin-type meter readings -- pinless moisture meters give you a qualitative reading. In other words, they tell you . A false reading on your moisture meter is when your meter gives you a reading, but you know it’s inaccurate. One factor that could cause false .
Even using the wrong grain calibration with a grain moisture meter, for barley instead of corn, as an example, will give you an inaccurate reading. Check to be sure that you .Along with moisture meter readings, hygrometer measurements provide proof that a space’s ambient conditions are brought back to a pre-loss state. . metals and salts cause false-positive readings. Regardless of the meter type you’re .
pinless moisture meter false readings
Frequently when I am checking a basement window, I am very conscious that the metal strips will cause a false reading, and the moisture meter will usually go to 100%. If at anytime you are in a drywall corner area or .
For example, Wagner Meter’s IntelliSense™ technology only reads moisture within the wood when set at ¾” depth, so it will give you a reading that’s closer to the actual moisture content than other pinless . 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.
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. .
The accuracy of pin and pinless moisture meters varies depending on their make and model, as well as the material used for their testing. 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.

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.
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.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: .
Understanding how to use a moisture meter is the first step toward getting measurements you can feel confident about. Taking Unquestionable Moisture Meter Readings . One of the biggest components of completing a survey is to understand moisture meter readings, what is normal, and (most importantly) when something is off. 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, “Ask stupid questions, get stupid answers.” Instead, we say “Use an uncalibrated meter, get an uncalibrated reading.”
If your meter is returning a false positive, the material would appear to be wet when it is actually making progress – or even dry. Moisture meters are subject to false positive readings for a number of reasons that are well documented in the industry. Non-invasive meters have more false positives than penetrating meters. 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 .
--all three hulls in your sample of three have normal moisture content and the moisture meter reading is being affected by the Unibond hull construction and gives a false indication. I don't know of any way to reach a conclusion about your data except to test more Unibond hulls, that is, to increase the sample size. 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 .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. When choosing a device to test moisture in drywall, look for the following: A Gypsum/Drywall Reading Scale.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.

Hello, When my home inspector performed a home inspection, he used a moisture meter to detect moisture around the walls of the shower, but I have not seen him using the moister meter to check the ceramic tile floor of the shower. Recently another home inspection was done and the inspector used a moisture meter to check the ceramic tile floors. Moisture . Reading depth is limited — from about one-fourth to three-fourths of an inch maximum, depending on the meter. Surface moisture can cause false readings. This can vary among brands and technologies, so it is important to have a basic understanding of these nuances when looking for a meter. The main advantage of the non-invasive moisture meter .
For pinless moisture meters, direct contact with metal to its probes gives readings that a material is wet. While non-penetrating moisture meters take moisture measurements in a different way for a different purpose, metal also interferes with their ability to locate moisture’s presence, also giving false-positive readings. Material Temperature A soil moisture meter is a simple tool to use, but there are certain things you need to know in order to get the correct readings because you can get wrong readings in certain situations. With that in mind, I put together this “guide” to .However, moisture meter scales can create some confusion. An understanding of the different moisture meter scales will help users to make the most accurate and efficient use of these tools.
