Question

Dissolved oxygen (DO) in a bioreactor is typically measured using a:

• A. Thermocouple
• B. pH electrode
• C. Polarographic electrode
• D. Conductivity meter

Hint:

To measure DO in a bioreactor, polarographic electrodes are typically used because of their sensitivity to oxygen and ease of calibration.

Answer 1

The Correct Option is C

A polarographic electrode is commonly used to measure dissolved oxygen levels in bioreactors, as it provides accurate, real-time readings of oxygen concentration in the culture medium.
