Series 2764 Differential DryLoc™ pH/ORP with Rebuildable Electrode Flat pH electrode, 3K ohm TC

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 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 available with 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. All versions can be mounted at any angle, even inverted.

The Signet 2764-2767 Differential pH & ORP electrodes are built to handle even the most extreme and harshest of chemical applications.A key feature is the reference electrode which is protected in a glass half-cell embedded in the reference chamber and is protected from compounds that may contain sulfides and metals. To ensure long service life, the reference features a refillable electrolyte chamber and a replaceable equitransferant salt bridge. The patented porous PTFE reference junction resists fouling, clogging and chemical attack.
