In the fermentation industry, pH electrodes are a very important detection tool. It measures the pH in the fermentation broth, helping to control the stability and efficiency of the fermentation process. When selecting a pH electrode, there are several factors to consider:
1. Measuring range: The range of pH value may be different in different fermentation processes. Therefore, it is necessary to choose a pH sensor that can cover the required range.
2. Response time: During the fermentation process, the pH value may change rapidly. Therefore, it is necessary to choose a pH electrode with a fast response time to ensure that changes are detected in a timely manner.
3. Corrosion resistance: The fermentation broth may contain some corrosive substances, such as acid or alkali. Therefore, it is necessary to choose a pH probe with strong corrosion resistance.
When using pH electrodes, the following points need to be noted:
1. Keep it clean: Before a…
