The RHCN Series controllers are
economical, panel-mounted
instruments designed to monitor
and control RH and temperature,
and feature dual relay contacts for
on/off control. An easily accessible
front panel switch toggles the large
LED display between a continuous
reading of either relative humidity or
air temperature. The RHCN features
2 standard recorder outputs of
10 mV/% RH and 10 mV/degree, for
simple interfacing with a computer
or datalogging device.
The solid state humidity and 100 Ω
Platinum RTD temperature sensors
are enclosed in a compact probe
which may be mounted virtually any
distance away from the controller.
