pH/ORP Wet-Tap Electrodes  – Overview

The Wet-Tap pH and ORP electrodes are sensors which are ideal for a wide range of applications where the installation and removal of the electrode can be performed without the need for system shutdown. The Signet 3719 pH/ORP Wet-Tap Assembly allows the installation and removal of pH or ORP electrodes under process pressure, without process shutdown during routine maintenance and calibration. Process isolation is achieved during electrode retraction with two sets of double O-ring seals on a unique and compact retraction assembly; no separate valve is required. The DryLoc connector with corrosion-resistant gold-plated contacts readily connects the sensor to the mating 2751 pH/ORP Smart Sensor Electronics or the 2760 Preamplifier. The robust polyarylsulphone (PAS) body and choice of bulb pH or flat ORP sensing elements allow a broad range of chemical compatibility for a wide range of applications. The quick temperature response is available in either a Pt1000 or 3 KΩ temperature sensor and allows compatibility with all Signet pH/ORP instruments.
