[Overseas Case] Improvement of Fermentation Management Using Optical DO Sensors

[Overseas Case] Improvement of Fermentation Management Using Optical DO Sensors

Examples of using oxygen measurement in a brewery! Reducing both the frequency of recalibration and the time required for that task.

At a major beer manufacturer, it became increasingly difficult to secure appropriate time frames for maintenance as annual beer production increased. Therefore, high-precision optical sensors from Hack were installed on the wort line. A 12-month test was conducted alongside diaphragm sensors for comparison, and the optical sensors demonstrated outstanding performance. The high-precision inline dissolved oxygen (DO) meter significantly reduced the frequency of service and maintenance. [Case Summary] ■ Challenge: Difficulty in securing appropriate time frames for maintenance ■ Solution: Transition from diaphragm sensors to optical DO sensors ■ Benefits - Significantly reduced frequency of service and maintenance - Replacement of the fluorescent spot itself reduced to once a year, and calibration decreased from 12 times a year to twice a year *For more details, please refer to the PDF document or feel free to contact us.
