3 Device description
The HM9 series of meters are electronic
measuring devices used to determine the
moisture level in wood. The meter indicator
displays wood moisture in %.
The principle of the capacitive and dielectric
measurement is used to determine the mois-
ture level. The process uses different dielectric
constants of dry, non-conductive materials
(approx. 2 – 10) water (approx. 80).
An electrical field generated under the sensor
surface (black plate on the bottom of the de-
vice) continues in the wood. The water con-
tained in the wood influences this electrical
field. This change is detected by the device,
evaluated and shown on the display as a
moisture value.
There are 21 predefined types of wood in the
device, which can be selected with the arrow
buttons. The device switches off automatically
after a few minutes.
