The Signet 2774-2777 pH and ORP electrodes are high performance sensors ideal for a wide range of applications. The unique foul-proof DryLoc® connector with gold-plated contacts is designed specifically for use with the Signet 2751 pH/ORP Smart Sensor Electronics or the 2760 Preamplifier. These dependable and highly responsive electrodes feature a PTFE double reference junction with potassium nitrate (KNO3 ) in the front chamber to block various poisoning ions such as Copper (CU2+), Lead (Pb2+), Mercury (Hg2+), and a large reference chamber that combine to extend the servicelife.
The positioning of the temperature element embedded in the pH sensing tip allows the temperature response to be quick and accurate. The electrodes are off ered 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 low temperature applications or where fast response is required. Due to the specially designed chambers which keep electrolyte in place, all sensor models can be installed at any angle, even inverted. The quick temperature response is available in either a
PT 1000 or 3KΩ temperature sensor and allows compatibility with all Signet pH/ORP instruments.
