The Signet 2724 – 2726 pH and ORP electrodes feature a patented reference electrode design and uses the unique foul-proof patented DryLoc connector. The large area PE reference junction and pathway is constructed to increase the total reference effectiveness and ensures long service life.

The DryLoc connector with foul-proof gold plated contacts readily connects the sensor to the mating 2760 preamplifier or the 2750/1 sensor electronics. The robust Ryton threaded sensor body and choice of flat pH, bulb pH or flat ORP sensing elements provides a broad range of chemical compatibility for a wide variety of applications.

There are two optional sensing versions, HF and LC available. 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 LC version can be used for low conductivity fluids (not less than 20 µS/cm).

The quick temperature response is available in either a PT-1000 or 3KΩ temperature sensor and allows compatibility with all GF Signet pH/ORP instruments. The 2724-2726 electrodes are general purpose sensors ideal for a wide range of applications. The sensors incorporate ¾” NPT or ISO 7/1 R¾ threads for installing into standard pipe-tees. They can also be mounted directly into GF Signet standard fittings.
