2. Confirm chemical compatibility before use.
3. Do not exceed maximum temperature/pressure specifications.
4. Wear safety goggles or faceshield during installation/service.
5. Do not alter product construction.
6. When using chemicals or solvents care should be taken and appropriate eye,
face, hand, body, and/or respiratory protection should be used.
Description
The +GF+ SIGNET 2760 pH/ORP Preamplifiers with DryLoc™ connectors are part of George Fischer Signet's growing arsenal of
sensors for industrial fluid measurement and control.
The 2760-1 and -2 Preampliers connects to three different families of pH and ORP electrodes to provide a stable and relaible signal
input to traditional +GF+ SIGNET instruments.
The 2760-3 and -4 models use the same package to link the same electrodes to third-party equipment that read a traditional millivolt
signal for pH measurement without temperature compensation or amplification.
