electrodes2764-2767 Differential DryLoc™ pH/ORP Electrodes

The Signet 2764-2767 Differential pH & ORP electrodes are built with the DryLocT connector a Ryton® body and TeflonT reference junction to handle even the most extreme and harshest of chemical applications. These differential 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 protected 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 TeflonT reference junction resists fouling, clogging and chemical attack. The other elements of the design 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, and a temperature device that is positioned at the tip of the measurement surface, making the temperature response of T95% less than 1 minute. Various temperature devices offered include 3KO, 300O, or PT-1000 RTD. The electrodes are used with the Signet 2750 Sensor Electronics, which provides a blind 4 to 20 mA output or using the digital (S3L) output may be used to connect to the Signet 8900 instrument. The electrodes can also be used with the Model 2760 preamplifier to connect to the Signet 5700, 8750, or other suppliers’ instruments.
