The MT28 moisture meter measures relative values, quickly pinpoints wet spots, and is widely used for humidity detection in wood panels, walls, ceilings, caravans, etc. ✘It reads 0-5% on drywall -You are unrecommened to make test on drywall, because the density of the drywall is too low to register a reading. It does work on Wall, but make sure the thickness of the drywall bigger than 19mm MT28C Pinless moisture meter for color display Pinless moisture meter Moisture meter RDINSCOS damp meter with color LCD display >>>>>Identify hidden problems, which will save potentially costly repairs. -The pinless moisture meter penetrates up to 0.75 inches and detects moisture conditions in walls to avoid living in a humid environment. -Not recommened to make test on pure drywall, because the density of the pure drywall is too low to register a reading(the actual readings will vary based on humidity and density of the material).If you need to measure it make sure it is thicker than 19mm (gypsum board overlap). The color display may be difficult to read in strong light—use the HOLD function to lock the reading and view it in a shaded area. Proper usage situation Keep fingers on the green-rubber grips Make sure there is no metal within 2inch of material being measured. Ensure the subject thickness up to 19mm. You are not recommended to make test on thin drywall directly !!!Note: The actual reading will vary depending on the humidity and density of the material Wrong usage situation There is metal, wire and pipe within 2inch of material being measured. Readings can be influenced by nearby metal, pipe or your hand. Why choose an induction moisture meter? Inductive measurement does not require damaging the material surface and can measure to a depth of approximately ≤19mm, making it suitable for quick screening. Why choose an induction moisture meter? Inductive measurement does not require damaging the material surface and can measure to a depth of approximately ≤19mm, making it suitable for quick screening. What is a “relative value”? Is it the actual moisture content? The relative value is a reference number used to quickly assess moisture differences and trends across different materials or areas. It does not represent the actual percentage of moisture content. What is a “relative value”? Is it the actual moisture content?

Why does repeated measurement at the same spot give different readings? Inductive measurements can be affected by slight changes in angle, pressure, or material density. This is normal—taking an average value is recommended for reference. Why does repeated measurement at the same spot give different readings?
