Page 4: Features Of Wood Moisture Tester Hm-540
1. Features of Wood Moisture Tester HM-540 This unit is a handy high-frequency moisture tester with integrated main unit and sensor section. Specifying the thickness of the wood and the specific gravity allows the moisture of various kinds of woods to be measured. The moisture can be measured just by pushing this device against an object to be measured, and therefore, the surface of the wood is not spoiled. -
