The 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. This device 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. Accessory adapter cables (sold separately) enable the 2759 to connect directly to Signet 2720 and 2760 preamplifiers, or 2750 pH/ORP Sensor Electronics. The adapters include a selector switch for pH or ORP simulation. The switch triggers automatic sensorrecognition software in Signet pH/ORP instrumentation.
