Thermo Scientific™ Orion Star™ A123 Dissolved Oxygen Portable Meter
Take simple, routine dissolved oxygen and temperature measurements with the Thermo Scientific™ Orion™ Star A123 Dissolved Oxygen Portable Meter, an easy-to-use and budget-friendly instrument 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.
- 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
