GF Signet 3-2766-1 pH Electrode, Bulb, 3kOhm Balco
The Signet 2764-2767 Differential pH & ORP electrodes are built with the DryLoc® connector, a Ryton® body, and PTFE reference junction to handle the most extreme and harshest of chemical applications.
These differential electrodes use a field-proven 3-electrode differential technique: the pH and reference electrodes are measured against a ground electrode, insuring a steady and stable signal. A key feature is the reference electrode, which is housed in a glass half-cell embedded in the reference chamber and is protected from compounds that may contain sulfides (S2-) and metals. To ensure long service life, the reference features a refillable electrolyte chamber
and a replaceable equi-transferant salt bridge, both easily serviced in the field. The patented porous
PTFE reference junction resists fouling, clogging and chemical attack.
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 surface, and a temperature device positioned at the tip of the measurement surface for a quick temperature response. Various temperature devices offered include 3 KO, 300 O, or PT1000 RTD.
The electrodes are used with the Signet 2750 Sensor Electronics, which provide a blind 4 to 20 mA output or use the digital (S3L) output to connect the Signet 8900 or 9900 instruments. The electrodes can also be used with the Model 2760 preamplifier to connect to the Signet 8750.
