The GF Signet 2759 pH/ORP Simulator is a battery-powered millivolt generator that simulates pH values of 4, 7, and 10, plus ORP values of ±700 mV. The GF Signet 2759 pH/ORP System Tester is useful as a troubleshooting aid and for general verification of system operation. However, it is not a substitute for periodic system calibration with pH buffers or test solutions.

Optional adapter cables enable the GF Signet 2759 pH/ORP System Tester to connect directly to GF Signet 2720 and 2760 preamplifiers, or 2750 pH/ORP Sensor Electronics. The adapters include a selector switch for pH or ORP simulation. The GF Signet 2759 pH/ORP System Tester's switch triggers automatic sensor recognition software in GF Signet pH/ORP instrumentation.
