Orion Star A323 RDO/DO

Features and Benefits

• Measure dissolved oxygen in percent saturation or mg/L with temperature using Orion RDO optical DO sensors or Orion polarographic DO sensors
• Calibrate dissolved oxygen using water-saturated air, air-saturated water, set value (Winkler titration), and zero point
• Automatically compensate DO readings using ATC temperature, manual input of salinity, and manual barometric pressure
• Informative, backlit, graphical display that is easy to read with clear screen instructions, simplifying operation
• Record critical measurements with stability indicator and optional reading modes – "Auto-Read" maintains a stable reading, "Continuous" shows changes with hold function, and "Timed" stores data at specific intervals
