    Take simple, routine dissolved oxygen and temperature measurements with the Thermo Scientific™ Orion™ Star A123 Dissolved Oxygen Portable Meter, an easy-to-use and budget-friendly instrument for basic dissolved oxygen analysis in the field. Calibrate polarographic DO probes using water-saturated air or custom value using Winkler titration. Quickly navigate setup menus and ensure consistent calibrations using the simple keypad layout and on-screen text prompts. Use the included electrode stand to easily place sensors in samples and simplify storage.

    Thermo Scientific Orion Star A123 Dissolved Oxygen Portable Meters combine simplicity with accuracy. A large LCD displays dissolved oxygen readings along with temperature. Icons provide quick updates on battery life and completed calibration status. Simple button layout and onscreen messages help with calibration and setup menu choices.

    • Large, informative screen clearly shows the main information, including DO reading in mg/L or % saturation, temperature in °C or °F, meter mode and battery life
    • Automatic temperature, manual salinity input and manual barometric pressure compensation for an accurate result
    • Don't miss a reading – AUTOREAD™ locks in the stable reading on your screen and ready indicator alerts when readings are stable
    • Two calibration options to meet your procedural requirements: water-saturated air method or a Winkler titration
    • Accepts Thermo Scientific Orion polarographic dissolved oxygen probes
    • Non-volatile memory holds up to 50 data points
    • Four AA batteries (included) provide over 2000 hours of operation or purchase the universal power adapter (sold separately) to run meter on AC power
