The Signet 2764-2767 Differential pH & 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 differential electrodes use the fieldproven 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 (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 PTFE reference junction resists fouling, clogging and chemical attack.
  • Wetted Materials: Ryton, PTFE, FPM, carbon graphite, glass
  • Connection: Durable DryLoc® with gold plated connections•Compatible Preamp/Sensor Electronics: 2750 and 2760
  • Compatible Instruments: Use the 2760 preamplifier with the Signet 5700 or 8750; Use the 2750 sensor electronics with the Signet 8900 or the 9900 Transmitter
  • Additional Features: Differential reference for additional protection in harsh chemicals; also quick temperature response
  • In-line Mounting styles: Use the sensors 1 inch thread to mount to any in-line tee
  • Submersible mounting: Available using the back of the preamplifier or sensor electronics•Applications: Water treatment, water quality monitoring, scrubbers, heavy metal removal, harsh chemicals, etc.
