Handheld Paper Moisture Meter is a device used to measure the moisture content of paper materials. The meter works by using a pair of electrodes that are placed on the paper surface, sending a small electrical current through the paper, and measuring the resistance to determine the moisture content. This type of meter is commonly used in paper mills, printing houses, and packaging industries to ensure that paper products are of high quality and have the desired moisture content. With the ability to quickly and accurately measure moisture levels, Handheld Paper Moisture Meter can help prevent issues such as paper jams, curling, and warping.
