Review on Dr.meter MT1905 Wood Moisture Meter - Digital Moisture Detector & Tester, Pin-Type Water Leak Detector for Wood Building Material, Firewood, Walls, Paper & Floors by Douglas Davis

I have no idea of the accuracy as I have no real standard for the measurement. It is used to control the moisture of floor slabs in the subsoil. The manual is very difficult to read because the calibration table is very small. For now, it seems acceptable to me for my use. Maybe one day I'll get a good quality gauge from someone else to compare to another, but until then I'll have to assume it's accurate enough for my use.
