Yushan has launched the latest fermentation fluorescence dissolved oxygen sensor for the fermentation industry, which adopts the world's leading fluorescence lifetime technology. Compared with traditional polarographic oxygen sensors, it has the characteristics of no preheating, no electrolyte, high precision, no interference, no maintenance and fast response. More environmentally friendly and many other technical advantages. It is acid and alkali resistant, can be sterilized at high temperatures, and meets the sterilization standards and steam sterilization standards.
Why does fermentation need to measure dissolved oxygen?
In aerobic fermentation in industrial production, the level of dissolved oxygen will affect the physiological metabolism of microorganisms, thereby affecting the growth of microorganisms and the synthesis of products. Research has confirmed that too low dissolved oxygen will inhibit the aerobic respiration process of microorganisms and increase by-products. Excessive oxygen supply will directly oxidize the substrate without product expression, increasing fermentation costs. Therefore, in the optimization and amplification of fermentation process monitoring, relevant parameter analysis is inseparable from dissolved oxygen data. Controlling appropriate dissolved oxygen can not only ensure the normal growth of bacteria, but also reduce stirring and aeration costs as much as possible.
The working principle of the Yushan fluorescence dissolved oxygen sensor
The Yushan fluorescence dissolved oxygen meter is based on the quenching principle of active fluorescence by specific substances in physics. The blue light emitted from a light-emitting diode illuminates the fluorescent material on the inner surface of the fluorescent cap. The fluorescent material on the inner surface is excited and emits red light. The phase difference between the red light and the blue light is detected and compared with the internal calibration value. , thereby calculating the concentration of oxygen molecules, and automatically compensating the temperature and air pressure to output the final value.
