3.2 COMPONENTS
The WP4C uses the chilled-mirror dew point technique to measure the water potential of
a sample. In an instrument that uses the dew point technique, the sample is equilibrated
with the headspace of a sealed chamber that contains a mirror and a means of detecting
condensation on the mirror. At equilibrium, the water potential of the air in the chamber is
the same as the water potential of the sample.
The WP4C main components include the display screen and sample chamber (Figure4 and
Figure5). A power cord and RS-232 communication cable can be plugged into the back of the
unit.
