##Orion Star A213 RDO/DO

Features and Benefits

• Measure dissolved oxygen in percentage saturation or mg/L with temperature using Orion RDO optical DO sensors or Orion polarographic DO sensors
• Calibrate dissolved oxygen using water-saturated air, air-saturated water, custom value (Winkler titration), and zero point option
• Automatically compensates for dissolved oxygen readings using ATC temperature, manual salt content input, and built-in barometer for barometric pressure measurement
• Informative, backlit graphical display that is easy to read with clear screen instructions, simplifying operation
• Record critical measurements with stability indicator and optional reading modes – "Auto-Read" maintains a stable reading, "Continuous" shows changes with hold option, and "Timed" stores data at specific intervals
• Eliminate the need for magnetic stirrer bars using a meter-controlled stirrer sensor (part no. 096019) for uniform mixing solutions
• Datalog stores up to 2000 measurements with date/time and options for sample ID and user ID
• Calibration log stores the last 10 calibrations
• Non-volatile memory ensures your data and settings are protected even during power loss
• Orion Star Com software facilitates data transfer to a computer via USB or RS232 connection
• Flexible power options with universal adapter or AA batteries
• IP54 enclosure is water- and dust-proof and can be wall-mounted if countertop space is limited
