Optical DO Sensors Improve Fermentation Management

As annual beer production goes up, a major brewer found it increasingly difficult to find appropriate time slots for maintenance interventions, especially in the recalibration of EC dissolved oxygen sensors in the wort lines.

Hach®’s high-range LDO in-line sensor was installed in a wort line. Side-by-side tests were run to compare the results to an EC sensor. Over 12 months, the high-range LDO performed extremely well.

The high range in-line DO sensors delivered a dramatic reduction in service and maintenance requirements. The LDO spot itself is changed only once per year and calibrated twice rather than 12 times per year.
