Signet 2724-2726 pH/ORP Electrodes

The Signet 2724-2726 pH and ORP Electrodes features 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 corrosion-resistant gold-plated contacts readily connects the sensor to the mating 2760 preamplifier or the 2750 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 available: HF and LC. The quick temperature response is available in either a PT1000 or a 3 KΩ temperature sensor and allows compatibility with all Signet pH/ORP instruments. The 2724-2726 electrodes are general-purpose sensors ideal for a wide range of applications. The sensors incorporate 3/4 NPT or ISO 7-1 R3/4 threads for installing into standard pipe-tees. They can also be mounted directly into Signet standard fittings.
