Log up to 5000 data point sets with time / date stamp and easily transfer logs to a printer or computer.

Take your measurements at the source with our premium line of portable meters. The Orion Star A323 RDO/DO portable meter offers an information-rich screen and user-friendly operation. This rugged, waterproof portable meter is ready to tackle the elements with you. Orion Star A323 RDO/DO portable meters are designed to be easy to use, dependable field meters that offer advanced features and functions including a 5000 point date log with sample ID and user ID options, calibration and high/low limit alarms and password-protected measurement methods. 

  • Measure dissolved oxygen in percent saturation or mg/L with temperature using Orion RDO optical DO probes or Orion polarographic DO probes
  • Calibrate dissolved oxygen using water-saturated air, air-saturated water, custom value (Winkler titration) and zero point options
  • Automatically compensate dissolved oxygen readings using ATC temperature, manual salinity input and built-in barometer for barometric pressure readings
  • Informative, easy-to-read backlit graphic display with clear onscreen instructions simplifies operation
  • Capture your critical readings with measurement stability indicator and selectable read modes – Auto-Read holds a stable reading, Continuous shows changing readings with hold option and Timed logs data at specific intervals
  • Data log collects and date/time stamps up to 5,000 measurement sets with optional sample ID and user ID
  • Calibration log stores ten most recent calibrations
