MT28 Moisture Meter 20mm depth
Product description
The MT28 moisture meter is a pinless detector for quick checks of relative moisture in building materials, walls and firewood. It uses an electromagnetic field to measure up to 20mm deep, helping spot leaks, damp patches and residual moisture after drying work. The first few readings are best taken away from metal fixtures, as the device is sensitive to conductive materials.
Key points
Compact and simple to use, the MT28 shows moisture levels on a three colour display, and sounds an alarm when readings exceed a threshold. The hold function freezes a measurement so you can note results, and the unit powers down automatically after 30 minutes to save battery life. A 9V battery is supplied with the device.

Usage tips
Begin by keeping the meter clear of metal fittings and wiring when scanning walls or timber, this avoids false readings. Press and hold the calibration button for at least 5 seconds to recalibrate before use, especially after battery changes or prolonged storage. If you need to compare spots, use the hold function to lock a reading while you move to the next area.
What to look for
It’s a good fit if you want an affordable handheld tool for routine damp checks and basic wood moisture screening, where deep invasive probes are not required. Take into account that it reports relative moisture rather than absolute laboratory values, so use it to locate problems and monitor changes rather than as a certified measurement.
