Aquametrix P/R60C-6 Differential pH/ORP Probes - Manual

The 60 series pH and ORP probes are
dependable industrial grade sensors
designed to provide accurate mea-
surement and longer service life under
the most demanding conditions. The
P60C-6 pH probes and R60C-6 ORP
probes incorporate all the benefits of
differential measurement found in oth-
er models of the 60 series, field proven
in thousands of installations. This tech-
nique uses two glass electrodes to
make the measurement differentially
with respect to a third metal electrode.
This second electrode is protected
from the process by a double junction
replaceable salt bridge. The result-
ing true differential measurement has
several advantages over conventional
probes: ground loop problems are vir-
tually eliminated, and the salt bridge is
easily replaced. If the internal solution
becomes contaminated, the probe can
be rejuvenated at modest cost by re-
placing the salt bridge and reference
solution. Automatic temperature com-
pensation is accomplished through
the use of an embedded thermistor
inside the tip of the ground rod. This
thermistor placement provides rapid
response for process temperature
variations. This unique probe mounts
in a standard 1 1/4” NPT tee, or in a
tank, through a specially designed
CPVC compression fitting. This tech-
nology provides several important ad-
vantages: the probe enters straight into
the fitting eliminating twisting of the
cable; the pipe size is only 1 1/4” NPT;
the insertion length is variable
between 7/8” and 5”; one mod-
el is used for both flow-through
and submersion tank-mount.
Installation does not require a pipe
wrench, strap wrench or thread seal-
ant on the probe. This helps to re-
duce down time for calibration. The
P/R60C-6 may be ordered with a
flat face electrode which fouls less
frequently and is easily cleaned.
The encapsulated preamplifier pro-
vides an output signal which can
be transmitted 3000 feet over in-
expensive cable. For greater dis-
tances, see the P65C data sheet
for the probe that encapsulates a
blind 4-20 mA two-wire transmitter
which can transmit a virtually unlim-
ited distance over a twisted pair cable.
