Do you work in the water damage, restoration industry? Perhaps you need to determine if your sheetrock has absorbed too much water to keep it in use? Mold spores are very unhealthy to ingest and inhale, so if your walls have taken in moisture of any amount from a recent water leak, you?ll want to verify which areas of the affected drywall should be replaced before it starts to mold. Mold growth on walls and ceilings is a sure sign of high humidity, condensation and/or a water leak hidden somewhere within the ceiling, walls, or finished flooring. This PREXISO moisture meter is designed for measuring moisture content in drywall, sheetrock and plaster walls, in addition to sawn lumber (paper and cardboard too), and materials that harden - like mortar and concrete. It displays the level of moisture content as soon as the metal prongs contact the material to be inspected. This makes it convenient for homeowners and professionals alike to check the moisture levels of their walls and projects, and can also measure ambient temperature. Being portable and easy to carry makes for a great addition to any toolbox. Use the two stainless steel pins by placing them into the surface of what you are measuring in order to capture a reading, but exercise caution, as the pins are sharp. If the unit is idle for more than 15 seconds it will turn itself off with its automatic shut off feature to save the battery life. To protect the pins from damage this moisture meter features a protective cover.
