Where to find it? Ross first discusses infrared meters which measure temperature [https://ift.tt/bLr840R]. A wall should have a consistent temperature, if it doesn’t, it may lack insulation or have water damage. For smaller leaks, Ross recommends a pinned or pinless meter. Pinned meters [https://ift.tt/40Rbosv] tend to be more accurate, however they do cause damage because it requires puncturing the material. They’re also more difficult to use with harder materials like concrete. While the pinless meter [https://ift.tt/aQsyONE] is not as accurate, it can be used across a variety of materials and will not cause damage. Combo meters [https://ift.tt/1okBKtr] are also available and include a pin and pinless fuction. Large areas of drywall and wood can be scanned for moisture with the pinless pad sensor. Once detected, the cap can be flipped to expose the pin sensors for more exact moisture readings. Looking for more step by step guidance on how to complete projects around the house?
