Orion Star™ A223 Dissolved Oxygen Portable Meter, Thermo Fisher Scientific
or call us at 1-800-727-0467
Record accurate and reliable dissolved oxygen and temperature measurements with the Thermo Scientific™ Orion™ Star A223 Dissolved Oxygen and RDO Portable Meter, ideal for a wide range of applications and advanced dissolved
oxygen analysis in the field. Use RDO optical or polarographic DO probes and calibrate using water-saturated air, air-saturated water, custom value (Winkler) or zero point options. Log up to 1000 data point sets with time / date stamp and easily transfer via USB or RS232 to a printer or computer. Waterproof meter ensures durable, rugged performance with an IP67-rated housing.
- 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 and Continuous shows changing readings with hold option
- Data log collects and date/time stamps up to 1000 measurement sets
- Non-volatile meter memory ensures your data and settings are protected, even with loss of power
- Orion Star Com software facilitates data transfer to a computer via USB or RS232 connections
- 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
Meters offer CE, TUV 3-in-1 and FCC Class A certifications and 3-year replacement warranty
