2734-2736 pH/ORP Electrodes

The Signet 2734-2736 pH and ORP Electrodes features a patented reference electrode design and uses the unique foul-proof patented DryLoc® connector. The large area PTFE reference junction, salt bridge and reference electrode are constructed to increase the total reference effectiveness, resist chemical attack, and ensure long service life.

The DryLoc® connector with corrosion resistant gold plated contacts readily connects the sensor to the mating 2750 sensor electronics. The robust Ryton® threaded sensor body and choice of flat, bulb pH, or flat ORP sensing elements provide a broad range of chemical compatibility for a wide variety of applications. There is an optional pH sensing version available for applications with HF. The HF version is for applications where traces of hydrofluoric acid (2% or less) will attack standard pH glass in levels of pH 6 and below.

The quick temperature response is available in a PT1000 temperature sensor and allows compatibility with the Signet 8900 and 9900 instruments. The 2734-2736 electrodes are ideal for a wide range of harsh applications. The sensors incorporate ¾ inch NPT or ISO 7/1-R 3/4 threads for installing into standard pipe-tees. They can also be mounted directly into Signet standard fittings, DN15 to DN100 (1/2 to 4 inch).

Fields of Application:
  • Water & Wastewater Treatment
  • Neutralization Systems
  • Effluent Monitoring
  • Sanitization Systems
  • Pool & Spa Control
