Differences Between Pin vs Pinless Moisture Meter

The moisture meter at sydney tools can check the moisture content of various materials, including gypsum boards, panels, and wood posts. Furniture manufacturers and other wood processors often use them to ensure that they are using high-quality products, while flooring manufacturers use them to determine the ideal humidity conditions when laying laminate or wood floors on concrete slabs or subfloors.

Moisture meter with pin

The moisture meter at Sydney Tools with a pin has two pins on the meter used to penetrate the test surface to the required depth. These meters use the principle of resistance to measure the MC percentage by measuring the contacts’ conductivity and usually display depths up to 5/16 inches. The end of the pin is relatively sharp, exposed, and penetrates the reading surface below the surface. This technique is generally regarded as an invasive process. For pin gauges, you can also get a reading by touching the surface with a test pin.


The non-contact moisture meter, named because it has no measuring needle, does not penetrate the material to read the reading, but the board on the back of the meter rests on the material, and the signal passes through it. The signal changes according to the material’s ability to store charge, which allows the moisture meter to determine the moisture content in the material. When testing drywall, the main advantage of the Pinless moisture meter is obvious. Moisture detection holes in the drywall can quickly turn them into Swiss cheese. The Pinless moisture meter at Sydney Tools can test moisture multiple times without damaging the drywall.

Test large flat areas, such as the entire floor

Non-contact moisture measurement equipment is very suitable for quickly and effectively measuring the moisture of large-area structures. Press the scanning plate on the floor, take the measurement, lift it and repeat the process elsewhere. Scanning markings scan a large area at a time, and each scan only takes a few seconds. This allows the user to check a massive area of ​​the structure relatively quickly.

On the other hand, a moisture meter with a pin can only check the moisture in a small area between the pins. In addition, they need to dig deeper into the tested material to obtain a complete picture. This usually means that more force is required to penetrate more complex materials, which increases stress and the risk of pin breakage. A smaller test area and additional workload will increase the time and effort required for large-area moisture measurement.

How does the pinless moisture meter work?  

The moisture meter at Sydney Tools without a pin works by touching the electromagnetic sensor pad on the surface of the wood but will not physically damage or damage the measurement surface. These meters can measure depths from the surface to 0.25″ or from 0.75″ to 1.5″. The moisture meter indirectly measures the moisture content of wood by measuring specific electrical characteristics of the wood. Fortunately, there are wood moisture meters that can work very accurately. Therefore, indirect humidity measurement with a good-quality moisture meter will provide you with sufficiently accurate readings so that you can make wise decisions about when and how to use wood.
