GF Signet 3-2754-1 pH Electrode, Flat, 3K Ohm

The Signet 2754-2757 pH and ORP Electrodes feature a unique foul-proof DryLoc® connector with gold-plated contacts designed specifically for use with the Signet 2750 and 2760 Sensor Electronics and preamplifiers. 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 electrodes are offered with either flat or bulb sensing elements. The flat versions allow sediment and particles to sweep past the measurement surface, minimizing the risks of abrasion, breakage and coating. The bulb versions can be used for general purpose applications and are also offered with a glass or plastic body for use with the 3719 Wet-Tap assembly.

The choice of a PT-1000 or 3KO temperature sensor allows compatibility with all Signet pH/ORP instruments.

The 2754-2757 electrodes are the flagship sensors of the Signet pH/ORP product line. They are all-purpose sensors ideal for a wide range of universal applications.
