The +GF+ SIGNET 3719 pH/ORP Wet-Tap allows installation and removal of pH or ORP electrodes without the need for process shutdown during routine electrode maintenance and calibration. Process isolation is achieved with a double O-ring seal on a unique and compact retraction assembly; no separate valve is required. A cam activated automatic locking mechanism, SafeLoc, and the short stroke design help to assure operator safety.
The +GF+ SIGNET 2754-2757 pH and ORP Electrodes feature a unique foul-proof DryLoc connector with gold-plated contacts designed specifically for use with the +GF+ SIGNET 2750 and 2760 Sensor Electronics. These dependable and highly responsive electrodes feature a large reference chamber volume and intelligent positioning of internal elements that combine to extend the service life.
The Signet 2764-2767 Differential pH & ORP electrodes are built with the DryLoc® connector, a Ryton® body, and PTFE reference junction to handle even the most extreme and harshest of chemical applications. These differential electrodes use the fieldproven 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 housed 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 PTFE reference junction resists fouling, clogging and chemical attack.
The SIGNET 2714 and 2716 pH Electrodes feature a combination design with measurement, reference, and temperature compensation element in one package. The plastic body construction and unique connection design makes removal and replacement of the electrodes so simple it can be done in seconds. For use with the SIGNET 2720 Pre-amplifier.
The SIGNET 2715 and 2717 ORP Electrodes feature a double-junction combination electrode with unique integral I.D. resistor for automatic sensor recognition by the SIGNET 8710 pH/ORP Transmitter. The chemically resistant CPVC body, and twist-lock connection make removal and replacement of electrodes fast and simple. For use with the SIGNET 2720 Pre-amplifier.

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 foul-proof 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 broad range of chemical compatibility for a wide variety of applications. There are two optional sensing versions, HF and LC, available. The quick temperature response is available in either a PT-1000 or 3Kohm 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.
Compatible with Signet 8900/9900 Instruments
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 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 (½ to 4 inch).
The +GF+ SIGNET 2750 and 2760 pH/ORP Sensor Electronics and Preamplifiers, featuring DryLoc connectors, provide a variety of functions to suit various requirements. The 2760 is a preamplifier that allows any DryLoc pH/ORP electrode to work with most +GF+ SIGNET instruments. It can also be used as a simple connector for use with other manufacturers’ instruments that do not require a preamplified signal.
The 2750 comes with the same pre-amplified signal as the 2760, but features two different outputs: a two-wire 4 to 20 mA loop output, or a digital (S3L) output which allows for longer cable lengths and is compatible with the +GF+ SIGNET 8900 Multi-Parameter Controller. The 2750 devices self-configure for pH or ORP operation via automatic recognition of the electrode type. The optional EasyCal feature allows simple push-button calibration and includes an LED indicator for visual feedback.
The DryLoc electrode connector found on both models quickly forms a robust assembly for submersible and in-line installations. NEMA 4X junction boxes are integral parts of the 2750 in-line version and are also available as accessories for both Models 2750 (submersible version) and 2760.
The Signet 2751 pH/ORP Smart Sensor Electronics featuring the DryLocR connector, is the solution for fieldfree calibration, out of range glass impedance and broken glass detection, alerting the operator to probe failure or maintenance needs.
