2764-2767 Differential DryLoc™ pH/ORP Electrodes

2764-2767 Differential DryLoc™ pH/ORP Electrodes
Features
• Differential design for
stable measurements
in the most aggressive applications
• Water-tight DryLoc™
connector with foulproof gold contacts
• Porous Teflon™
reference junction
• Rebuildable reference
electrode
• Solution ground
Description
The +GF+ SIGNET 2764-2767 Differential pH &
ORP electrodes are built with the DryLoc™ connector
a Ryton® body and Teflon™ reference junction to
handle even the most extreme and harshest of
chemical applications. These differential electrodes
use the field-proven 3-electrode differential technique: the pH and reference electrodes are
measured against a ground electrode, insuring a
steady and stable signal.
The key feature of the differential design is the
reference electrode. The reference element is
protected in a glass half-cell embedded in the
reference chamber and is protected from compounds that may contain sulfides (H2S) and metals,
including lead, mercury, and silver. To ensure a long
service life, the reference features a refillable
electrolyte chamber and a replaceable
equitransferant salt bridge, both easily serviced in
the field. The patented porous Teflon™ reference
junction resists fouling, clogging and chemical
attack.
The other elements of the design are the solution
ground, the pH/ORP electrodes, and the
temperature element. The solution ground
eliminates noisy measurements by draining
electrical current away from the reference
electrode. The pH/ORP electrodes are designed
with a flat or bulb measurement surface, and a
temperature device that is positioned at the tip of
the measurement surface, making the temperature
response of T95% less than 1 minute. Various
temperature devices offered include 3KΩ, 300Ω,
or PT-1000 RTD. The electrodes are used with the
+GF+ SIGNET 2750 Sensor Electronics, which
provides a blind 4 to 20 mA output or using the
digital (S3L) output may be used to connect to the
+GF+ SIGNET 8900 instrument. The electrodes
can also be used with the Model 2760 preamplifier to connect to the +GF+ SIGNET 5700, 8750,
or other suppliers’ instruments.

Electrode Key Feaures and Benefits:
•
•
•
Glass encased reference electrode
protects the Ag+ element from reacting
with certain chemical compounds that
typically leach into the reference chambers. Keeps the pH/ORP reading stable.
Large volume reference electrolyte
chamber resists dilution over time for a
long service life. Chamber is refillable.
Salt Bridge serves as a double reference
junction and is the first line of defense to
keep out process chemicals from the
reference electrolyte chamber. It is built
with a porous Teflon reference junction
which is highly compatible to chemicals ,
resists fouling and build-up of dirt.
•
Ryton body for chemical compatibility to
most harsh chemicals. Also able to
withstand high temperatures.
*
DryLoc connector with corrosion resistant
gold pins for quick and easy sensor
removal.
•
Capillary TC (temperature sensor)
embedded in tip of pH/ORP electrode
for quicker temperature response than
most other electrodes on the market.

Electrode Key Feaures and Benefits:
A differential electrode solves many common problems typically experienced by standard pH/ORP electrodes at
troublesome measuring points. See the table below to find the common problem, cause and effect, and the Differential
pH/ORP electrode solution.
Standard pH/ORP electrode
problem:
Reading slowly drifts over time and/or
responds slowly
Reading slowly drifts over time and/or
becomes erratic
Cause and Effect
The Differential Electrode Solves the Problem!
• Chemical attack from Hg++, Cu+, Pb++, ClO4- or
other compounds which dilute the KCl reference
electrolyte concentration.
• Salt bridge will slow or stop attack. If attacking ions
penetrate the salt bridge and affect the KCl, simply refill
KCl solution
• Reference junction gets clogged from oils, grease, and
dirt from the process.
• Readings do not drift due to stable differential reference
design, however may require cleaning or replacement of
the salt bridge if electrode gets too dirty.
• Chemical attack of the Ag+ reference billet from Br-, I-,
CN-, and S- compounds.
• Will not affect electrode due to Ag+ element protected
in glass encased reference electrode.
• Clogged reference and slowed reading from silver
compounds forming on the inside of the reference
electrode from Ag+ of reference element reacting and
precipitating AgS, AgBr, AgI, AgCN, or other silver
compounds.
• Will not affect electrode due to Ag+ element protected
in glass encased reference electrode
Reading suddenly and unexpectedly shifts • Stray electrical currents in the process liquid; Ag+
reference element picks up current and shifts reference
reading, resulting in shifted pH reading. The Ag+ element
will eventually become totally stripped. Process must be
properly grounded or place metal rod close to electrode.
• Will not affect electrode due to Ag+ element protected
in glass encasement; also, electrode has a built in
solution ground, so if there is a stray current, it will not be
seen by the electrode
2759 pH/ORP System Tester
The +GF+ SIGNET 2759 pH/ORP Simulator is a battery-powered millivolt generator that
simulates pH values of 4, 7 and 10, plus ORP values of ± 700 mV. This device is useful as a
troubleshooting aid and for general verification of system operation. It is not a substitute for
periodic system calibration with pH buffers or test solutions. Accessory adapter cables (sold
separately) enable the 2759 to connect directly to +GF+ SIGNET 2720 and 2760
preamplifiers or 2750 pH/ORP Sensor Electronics. The adapters include a selector switch for
pH or ORP simulation. The switch triggers automatic sensor-recognition software in +GF+
SIGNET pH/ORP instrumentation.

In-Line Installation
•
The 2764-2767 electrodes feature a thread close to the sensor end which
allows the sensor to thread directly into a standard MNPT pipe tee.
• Electrodes must be immersed in liquid. Keep pipe full at all times to avoid
dehydration.
• Make sure to observe the electrode’s mounting angle requirements.
