Some understanding of ph meter digital
For many people, they are not unfamiliar with ph meter digital and know how to use it, but they still often ignore many problems that need attention. Then, let’s introduce the related precautions of ph meter digital in detail:
1. Pay attention to the circuit protection. When the ph meter digital is not working, its input should be short-circuited to avoid damage.
2. The glass electrode socket of the ph meter digital must be kept clean and dry at all times, absolutely avoid contact with harmful gases such as salt spray and acid fog, and it is strictly forbidden to touch any aqueous solution on the glass electrode socket, which will cause high input impedance of the ph meter digital.
3. Pay attention to the storage of the pH electrode. It is better to cover the glass probe with a plastic sleeve filled with 3mol/L potassium chloride solution.
