- 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
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.
