The HM-530 is Kett's newest and smallest Wood Moisture Tester. It is totally nondestructive to the surface of the wood being measured and can measure moisture deep inside the wood. Using a built-in, powerful microcomputer, it displays direct readings. Any type of lumber can be measured by simply adjusting dials on the face of the instrument for depth, density and temperature. The tester comes with a Manual listing the density of hundreds of wood types. The HM-530 has been granted ISO 9001 approval - a valuable international quality assurance standard.
