Take simple, routine dissolved oxygen and temperature measurements with the Thermo Scientific™ Orion Star™ A123 Dissolved Oxygen Portable Meter. This instrument is easy-to-use and budget-friendly, designed for basic dissolved oxygen analysis in the field. Calibrate polarographic DO probes using water-saturated air or custom value using Winkler titration. Quickly navigate setup menus and ensure consistent calibrations using the simple keypad layout and on-screen text prompts. Use the included electrode stand to easily place sensors in samples and simplify storage.

Thermo Scientific Orion Star A123 dissolved oxygen portable meters are a simple, economical solution for your routine outdoor sample analysis. Featuring an emphasized measure key, selectable read modes and measurement stability indicator, our basic Orion Star A123 dissolved oxygen meters are designed to deliver measurements you can trust at an affordable price.
  • Measure dissolved oxygen in percent saturation or mg/L with temperature using polarographic DO probes
  • Calibrate using water-saturated air or custom value (Winkler titration)
  • Automatically compensate DO readings using ATC temperature, manual salinity input and manual barometric pressure
  • Simplified, easy-to-read display shows main measurement with temperature, stability indicator and electrode condition icon
  • User-friendly operation with basic calibration text prompts
  • Easily recall calibration data for procedure checks
  • Non-volatile memory preserves 50 point internal data log and meter settings, even with loss of power
  • Flexible power options with AA batteries or optional universal power adapter
  • IP67-rated housing is waterproof for rugged field operation
  • Meter kits include hard-sided field case and protective meter armor with electrode holders, adjustable wrist/belt strap and built-in meter stand
  • Meters offer CE, TUV 3-in-1 and FCC Class A certifications and 3-year replacement warranty
