INSTALLATION
pH 500 and mV 600
offer a multitude of
possibilities, from
single and dual set-
points to ON/OFF or
proportional dosage,
isolated outputs with
user-selectable zoom,
bi-directional RS232,
recorder outputs in
mAmps and volts.
In addition, pH 500
and mV 600 are both
equipped with the ex-
clusive differential
input.
In a system with poor
grounding, it is
possible to have a
ground current flow-
ing through the
reference junction.
This can cause a rapid
degradation of the
electrode. The Hanna
differential input
reduces the likelihood
of ground loops.
See the diagram for a
recommended instal-
lation.
