The Signet 2760 DryLoc® pH/ORP Preamplifiers with DryLoc® connectors are part of Signet's growing line of sensors for industrial fluid measurement and control. There are two styles of preamplifiers, and each is available with NPT or ISO threads at the cable outlet. They all connect to four different families of pH and ORP electrodes to supply an amplified mV (analog) signal to Signet instruments.
This manual provides installation instructions for Signet 2760 DryLoc pH/ORP Preamplifiers, including in-line, wet-tap, and submersible setups. It details wiring to Signet instruments and compatible electrodes. Safety precautions and environmental specs are included.
Technical specifications cover electrical parameters, enclosure ratings, materials, and operating/storage temperatures. The document also includes diagrams for assembly and notes on chemical compatibility and warranty conditions.
