Thermo Scientific Orion STARA2230 is the Orion Star A223 portable dissolved oxygen meter designed for reliable laboratory and field DO analysis.
The meter supports both Orion RDO optical dissolved oxygen probes and polarographic dissolved oxygen probes, providing flexibility for different water quality applications.
Dissolved oxygen can be measured in concentration or percent saturation together with temperature. The instrument also includes a built-in barometer for automatic pressure compensation and supports manual salinity correction.
For RDO optical measurement, the concentration range extends from 0.00 to 50.00 mg/L. Polarographic DO measurement supports a range from 0.00 to 90.00 mg/L.
The meter supports calibration using water-saturated air, air-saturated water, manual Winkler titration values or zero-point calibration.
Its IP67 waterproof housing is suitable for demanding field environments. The graphic backlit LCD provides clear measurement information and status indicators.
Up to 1,000 data sets can be stored with date and time stamps, and measurement results can be transferred to a computer or printer through USB or RS232.
STARA2230 includes the Star A223 meter, four AA batteries, quick start documentation, computer interface cable and meter test certificate. Dissolved oxygen probes are sold separately.
