Thermo Scientific™ Orion Star A123 Dissolved Oxygen Portable Meter Kit with Polarographic DO Sensor (3 meter cable), Maintenance Kit, Meter Armor and Field Case

Take simple, routine dissolved oxygen and temperature measurements with the Thermo Scientific™ Orion Star™ A123 Dissolved Oxygen Portable Meter. This instrument is easy-to-use and budget-friendly, designed 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.
