INSTALLATION

pH 502 and mV 602
offer a multitude of
possibilities, from single
and dual setpoints to
ON/OFF or PID dos-
age, isolated outputs
with user-selectable
zoom, bi-directional
RS485, recorder out-
puts in mAmps and
Volts.

In addition, pH 502
and mV 602 are both
equipped with the ex-
clusive differential
input.

In a system with poor
grounding, it is possible
to have a ground cur-
rent flowing through
the reference junction.
This can cause a rapid
degradation of the elec-
trode. The Hanna
differential input re-
duces the likelihood of
ground loops.

See the diagram for a
recommended installa-
tion.
