The GF Signet 2764-2767 differential pH and ORP electrodes are built with the DryLoc® connector, a Ryton® body, and PTFE reference junction to handle even the most extreme and harshest of chemical applications.
These GF Signet 2764-2767 differential pH and ORP 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 housed in a glass half-cell embedded in the reference chamber and is protected from compounds that may contain sulfides 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 PTFE reference junction resists fouling, clogging, and chemical attack.
The other elements of the design of the GF Signet 2764-2767 Differential pH and ORP Electrodes 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, making the temperature response of T 95% less than 1 minute. Various temperature devices offered include 3K Ohms, 300 Ohms or PT-1000 RTD. The electrodes are used with the GF Signet 2750 Sensor Electronics, which provides a blind 4 to 20 mA ouput or using the digital output may be used to connect to the Signet 8900 instrument. The electrodes can also be used with the GF Signet 2760 preamplifier to connect to the GF Signet 5700, 8750, or other suppliers' instruments.
