Thermo Scientific™ Orion Star™ A323 Dissolved Oxygen Portable Meter
Shop All Thermo Scientific ProductsGet high accuracy and premium performance everywhere you need it with the Thermo Scientific™ Orion Star™ A323 Dissolved Oxygen and RDO Portable Meter. This instrument is designed for a wide range of dissolved oxygen and temperature testing and field applications. Evaluate samples in the most demanding locations using this waterproof meter with IP67-rated housing. Use an RDO optical or polarographic DO probe and calibrate using water-saturated air, air-saturated water, custom value (Winkler) or zero point. Log up to 5000 data point sets with time/date stamp and easily transfer logs to a printer or computer.
- Measure dissolved oxygen in percent saturation or mg/L with temperature using Orion RDO optical DO probes or Orion polarographic DO probes
- Calibrate dissolved oxygen using water-saturated air, air-saturated water, custom value (Winkler titration) and zero point options
- 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 your critical readings with measurement stability indicator and selectable read modes — Auto-Read holds a stable reading, Continuous shows changing readings with hold option and Timed logs data at specific intervals
- Data log collects and date/time stamps up to 5000 measurement sets with optional sample ID and user ID
- Calibration log stores 10 most recent calibrations
- Non-volatile meter memory ensures your data and settings are protected, even with loss of power
