Review: Great tool - Great tool! It’s easy to use and the display is easy to read. accurate readings. Doesn’t leave pin holes in wood to test moisture. Would recommend
Review: Versatile Damp Meter - Particularly good for checking how high damp is rising in a solid wall and works effortlessly through wall paper/paint etc. Purchased to check extent of flood damage. Worth every penny. Also excellent at confirming extent of relative moisture in a screed flood. Simple to use and not potentially damaging as with the pronged varieties. Like all tools you need to understand it strengths and limitations; what is is telling you and how best to interpret the figures. Metalwork and pipes skew the readings. It doesn't read surface moisture but the relative permittivity of the material (which changes with moisture) to about 19mm depth, whereas probes measure electrical conductivity from the surface. Appears rugged, in decent box with cloth bag. Excellent screen display. Can be set for several materials such as masonry and wood using the Mode key.

## Questions & Answers

**Q: Why choose an induction moisture meter?**
A: Inductive measurement does not require damaging the material surface and can measure to a depth of approximately ≤19mm, making it suitable for quick screening.

**Q: What is a “relative value”? Is it the actual moisture content?**
A: 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.

**Q: Why is the MT28C damp meters screen hard to read under sunlight?**
A: LCD color displays perform poorly under direct sunlight. It is recommended to shade the screen with your hand or press the HOLD button to lock the reading, then view it in a shaded area.

**Q: Why does repeated measurement at the same spot give different readings?**
A: 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.

**Q: Can the device be recharged?**
A: No. This instrument uses a 9V battery for power. It is easy to install and can be replaced as needed.

### ⭐⭐⭐⭐ Saved me spending hundreds on a survey, could walk away when house vendors told fibs.
*by H***K on 16 January 2026*

Great, I could use it, but note the presecence of metal in a wall may through it off. Going on viewings for next home move and was sick of seller telling fibs saying it was dry, the damp metre doesn't lie and for the money on an offer it could save you hundreds on unnecessary survey fees. UPDATE: Still works well if you follow the instructions.
