+GFSignet 2764/2765/2766/2767 Differential DryLoc™pH/ORP Electrodes

Product Description:

The +GF+ SIGNET 2764-2767 Differential pH & ORP electrodes are built with the DryLoc™ connector a Ryton® body and Teflon™ 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 Teflon™ 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 +GF+ 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 +GF+ SIGNET 8900 instrument. The electrodes can also be used with the Model 2760 preamplifier to connect to the +GF+ SIGNET 5700, 8750, or other suppliers’ instruments.
