  Orion 4-Star pH/RDO Portable Meter


Thermo Scientific Orion Star meters with RDO require no membranes.  Maintenance is just a simple cap replacement.  This easy-to-use feature is great for measurements from effluent, aeration basins and even influent, as the sensor is not affected by color or turbidity. 

   Product Detail


  • Dissolved oxygen, pH and temperature measurement capabilities
  • pH calibration of up to 5 points with calibration alarm and automatic buffer recognition of USA, NIST and DIN buffers
  • Temperature calibration capability for pH
  • Data storage for 750 data sets with time and date stamping

All RDO Meters feature:

  • Dissolved oxygen level measurements using optical DO technology
  • No membranes to change - once-a-year cap replacement
  • Calibrate for dissolved oxygen using water-saturated air, air-saturated water, zero point, or at a custom point with Winkler titration
  • Built-in barometer for automatic pressure correcting with option for manual correction for dissolved oxygen readings
  • RS232 port for easy data downloading and software updates
  • Simultaneous display of measured values on the backlit display
  • IP67-rated housing
  • Four AA batteries to provide over 1000 hours of operation in Auto-Read™ mode
  • 3-year warranty on meter and RDO probe body
  • 1-year warranty on RDO sensor cap
