GF Signet 3-2777-1 DryLoc ORP Electrode 3-2777-1
Signet 3-277X-X Threaded DryLoc pH/ORP Electrodes.MOUNTING: In-Line / Vertical / Submersible, MAX PRESSURE: 100 psi (6.9 bar), COMPATIBILITY: Signet Models 2750 and 2760.
GF Signet 3-2777-1 Threaded DryLoc pH-ORP Electrodes. Wetted Materials: Ryton, PTFE, FKM, glass, Connection: Durable DryLoc® with gold plated connections, Compatible Preamp/Sensor Electronics: 2750 and 2760.
The Signet 2774-2777 pH and ORP Electrodes feature a unique foulproof DryLoc® connector with gold-plated contacts designed specifically for use with the Signet 2750 and 2760 preamplifiers and sensor electronics. These dependable and highly responsive electrodes feature a PTFE double reference junction with KNO3 in the front chamber to block various poisoning ions. Embedded positioning of the temperature element in the pH sensing tip allows the temperature response to be quick and accurate. The electrodes are offered with either flat or bulb style sensing elements. The flat versions allow sediment and particles to sweep past the measurement surface, minimizing risks of abrasion, breakage and coating. The bulb versions can be used for general purpose applications. Due to the specially designed chambers which keep electrolyte in place, all versions can be mounted at any angle, even inverted.
