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 tradiGF+ 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.
