USER GUIDE
6
This eld penetrates the material under test. The very
small alternating current owing through the eld is
inversely proportional to the impedance of the material.
The instrument detects this current, determines its
amplitude and thus derives the moisture value.
In Hygro-i probe mode, the CMEXpert II determines
the capacitance of the RH probe sensor which varies
with the relative humidity of the testing environment.
The CMEXpert II displays this capacitance as percentage
relative humidity (%RH). It also measures temperature
and displays dew-point temperature and mixing ratio.
In Pin probe mode the CMEXpert II is a resistance-type
pin-meter for determining the moisture content of wood
and wood-based products.
