Description

Take simple, routine dissolved oxygen and temperature measurements with the Thermo Scientific™ Orion Star™ A113 Dissolved Oxygen Benchtop Meter. This instrument is easy-to-use and budget-friendly, designed for basic dissolved oxygen analysis in the lab. 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.

Features and Benefits

• Automatic temperature, manual salinity input and manual barometric pressure compensation for an accurate result
