Yeast is used to make beer. In the fermentation process, the yeast produces beer by breaking down the sugar content of wort into alcohol and carbon dioxide. Because the function of this enzyme is influenced by pH, pH control is very important for efficient fermentation. In addition to pH, dissolved oxygen meters are used to manage carbon dioxide, thereby managing oxygen, which is an oxidative factor in beer, at very small concentrations. In addition, the manufacturing process is optimized by using conductivity meters, etc. HORIBA is lineup with a wide range of meters and sanitary sensors, and responds to a wide variety of measurements.
