Optical sensing of dissolved oxygen in brewing applications is being presented as a more precise, lower-maintenance alternative to long-established amperometric technology
The monitoring of dissolved oxygen content is essential for the brewing process. If large amounts of dissolved oxygen are present in finished beer, oxidation processes take place that negatively affect the beer’s flavor and cause premature product aging. Dissolved oxygen (DO) is a relative measurement of the amount of oxygen that is dissolved or carried in a given medium.
