Optical Dissolved Oxygen Controller, 1/4-DIN, 110/220 VAC

Compact optical dissolved oxygen controller simultaneously measures and displays dissolved oxygen and temperature. Selectable measurement modes allow readings to be displayed in mm Hg, % saturation, ppm, or mg/L. Autoranging function automatically provides the best possible resolution for the measured range. Controller features two independent high/low relays with adjustable set points, two independent 0/4 to 20 mA current outputs, and two SPST autoclean relays for robust control applications. Use the current outputs to send dissolved oxygen and temperature measurements to a recorder, datalogger, or PLC. Control relays let you trigger externally powered devices such as pumps, valves, or aerators. Optical technology reduces probe maintenance costs Greater measurement stability than either galvanic or polarographic technologies Dual current outputs allow measured readings to be exported to a datalogger or PLC Autoclean relay adds convenience
