YSI Webinar | How Dissolved Oxygen Sensors Work

October 29, 2019 How Sensors Work

From sustaining aquatic life to the tight control of wastewater treatment, dissolved oxygen (DO) plays a role in nearly every water quality application.

In this educational webinar, we discuss:

  • Applications where DO measurement is critically important,
  • The evolution of sensor technologies for measuring DO in the field,
  • The underlying principles of how the most current optical DO sensors work, and
  • Real-world examples that demonstrate both the value and limitations of field-based measurements of DO.

In addition, others (like me) are progressively like Beethovenian and continue to change and clean the substance for a long time. Be that as it may, as a young scientist, it is perfect to be a combiner and do some of both: plan out your papers and form as much as possible at that first sitting, and a short time later, as the concentrations underneath illustrate, you can give it and tinker to it. Taking everything into account, at some point or another, you ought to send it in for a review. You won't get residency with some nearly completed papers. I can vouch for that!
