Reliably measure dissolved oxygen (RDO optical / polarographic) and temperature with the Orion™ Star™ A213 RDO/DO Benchtop Meter for advanced laboratory analysis.

• 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 critical readings with measurement stability indicator and selectable read modes
• Auto-Read mode holds a stable reading, continuous mode shows changing readings with hold option, and Timed mode logs data at specific intervals
• Data log collects and date/time stamps up to 2000 measurement sets with optional sample ID and user ID
• Calibration log stores ten most recent calibrations
• Three-year meter warranty

Record accurate and reliable dissolved oxygen and temperature measurements with the Orion™ Star™ A213 dissolved oxygen and RDO benchtop meter.

These easy to use, dependable laboratory meters are equipped with advanced features and functions. Selectable read modes and stability indicator provide flexibility and control over testing. All critical data is shown with measurements, including temperature, date and time, read type, measurement stability, and active calibration information. Onscreen calibration and setup instructions can be displayed in several local languages with new languages added through software updates. Navigation is fast and simple due to the comprehensive keypad with menu-specific function keys, dual purpose scroll/shortcut keys, plus power, measure, log view, and stirrer keys that ensure easy operation. All setup menus are in one location with direct access using a single shortcut key to quickly access, evaluate, and change measurement and instrument settings. Eliminate the need for magnetic stir bars using the meter-controlled stirrer probe or Orion Auto-Stir BOD probe to uniformly mix solutions. Flexible power options with universal power adapter or optional AA batteries.

IP 54-rated housing resists dust and splashes, and can be wall-mounted. Non-volatile meter memory ensures data and settings are protected, even with loss of power.

The unit is ideal for a wide range of applications and advanced dissolved oxygen analysis in the lab. Use an RDO optical or polarographic DO probe for ultimate flexibility in sensors. Calibrate using water-saturated air, air-saturated water, custom value using Winkler titration, or zero point options. Log up to 2000 data point sets with time/date stamp and easily transfer calibration and data logs via USB or RS232 to a printer or computer.
