This pH controller is configured for 110 V AC, 0 to 14 pH, 4 to 20 mA. It has accuracy of 0.1 mV @ 25°C. It suits environmental ph monitoring and process ph control.
This pH controller is configured for 110 V AC, 0 to 14 pH, 4 to 20 mA. It has accuracy of 0.1 mV @ 25°C. It suits environmental ph monitoring and process ph control.
This microprocessor-based family of pH panel mounted controller is designed for a wide variety of environmental monitoring applications. The units feature automatic or manual temperature compensation of pH, two 5 A mechanical relays and a choice of a scalable 4 to 20 mA, or 0 to 20 mA control or recording output or a 0 to 10 V output. For ease of operation all calibration and parameter setpoints are selectable through the front keypad.
