The 2756 - 2757 Wet-Tap electrodes are all-purpose sensors ideal for applications where the probe can be removed for cleaning and maintenance without the system shutdown. They feature a unique foul-proof DryLoc connector with gold-plated contacts, designed specifically for use with the Signet 2751 Smart Sensor Electronics, and 2760 Preamplifier. These dependable and highly responsive electrodes feature a large reference chamber and intelligent positioning of internal elements that combine to extend the service life. The electrodes are offered with a bulb sensing element that can be used for general purpose applications where a fast response is required even at low temperatures. The choice of a PT1000 or 3 KΩ temperature sensor allows compatibility into all Signet pH/ORP instruments. The 3719 Wet-Tap assembly allows installation and removal of electrode even under process pressure without the need for process shutdown.
