PHCN-201 is a simple-to-operate
pH controller specially designed for
applications where space or costs are
a major concern. Thanks to its compact
size of only 8 x 5 cm (3 x 2"), PHCN-201
can be mounted in confined spaces and
right next to tanks or vats. The low cost
of the meter will also make it possible
for processes that up to now were
manually maintained to be controlled
automatically, saving considerable
time and money. Measurements are
displayed in large digits on the LCD and
LED lights indicate the exact status of
the controller, even from a distance.
PHCN-201 also incorporates a
bi-directional relay. Through a simple
jumper on the rear of the meter, the
operator can select acid dosage,
which means the relay is activated with
measurements above the setpoint,
or alkaline with relay closed when
measuring below the setpoint. In order
to adjust the setpoint from 0 to 14 pH
or to calibrate meter at any point on
the scale, simply turn the relevant
trimmer right on the front panel. The
controller is easy to use and to install.
Any combination pH electrode with a
BNC connector can be hooked up to the
meter. The meters are available in three
models to best suit your application.
You can choose from the 100 to 110V
or the 220 to 240V operated model.
For those who prefer to operate at low
voltage, there is also the 12 Vdc version
with the transformer included in the low
cost of the meter.
