from Thermo Scientific


Model Orion Star A223
The Thermo Scientific Orion Star A223 RDO/Dissolved Oxygen Portable Meter makes necessary testing easier. Its durability and dependability make it a great choice for samples every day, anywhere.

Get the readings that you need where you need them with the Thermo Scientific Orion Star A223 RDO/Dissolved Oxygen Portable Meter. The large, backlit graphic LCD display shows dissolved oxygen in percent saturation or concentration with temperature and electrode status, time, date and calibration points.

Features and Benefits
  • Anyone can use this meter with its plain language screen prompts, soft keys that update for easy selection and a multilanguage interface that supports English, Spanish, French, Italian, German and Chinese.

  • No need to worry about DO probe compatibility – the meter accepts and automatically recognizes Orion
    polarographic and RDO optical/ luminescence-based probes.

  • Accurate results are easy with automatic temperature, manual salinity and automatic/manual barometric pressure compensation.

  • Don't miss a reading – AUTO-READ™ locks in the stable reading on your screen and ready indicator alerts when readings are stable.

  • Calibrate using water-saturated air, air-saturated water, a Winkler titration or zero point calibration.

  • Non-volatile memory holds up to 1000 data points with time and date stamp.

  • Easily transfer data and keep meter software up-to-date with the USB and RS232 ports and complimentary data analysis software.

  • Four AA batteries (included) provide over 800 hours of operation or purchase the universal power adapter (sold separately) to use AC power.

  • Perfectly portable, waterproof and protected to take anywhere with a IP67-rated housing.

  • 3 year meter replacement warranty.
