You have prepared all the materials for DIY your house. But whether the environment you live in is humid or too dry. This has become your current problem. Because you can’t adapt them to the environment. Too humid ground will make the wood board moldy and spotty in a short time, while too dry will make the wood board crack. Don’t worry, a short article will help you choose the moisture meter that’s right for you. Pinless moisture meters and pin-type moisture meters are the two most common moisture measuring instruments. Pin-type moisture meters can be directly inserted into the wood or material to be measured. The instrument measures the resistance between the built-in pins through electrodes. The size of the resistance is affected by the moisture content of the material. By observing whether the resistance is close to the standard value of the material, it can be judged whether the wood or material meets the standard. The working principle of the pinless moisture meter is relatively simple to understand. Its electrode plate only needs to contact the surface of the material to work, and the relative moisture content of the material is measured by the generated electric field.
