Precautions for china ph meter digital
china ph meter digital is also called acidity meter, which is often used to measure and detect the acidity and alkalinity of liquid media. It is widely used in industry, agriculture and environmental protection. If the measured data is inaccurate, it will have serious consequences for engineering or the environment. The correct use of china ph meter digital is particularly important, and it is necessary to strictly follow the correct method and sequence in order to obtain more accurate measurement data.
Although many people are not unfamiliar with china ph meter digital and know how to use it, there are still many issues that need attention. Then I will introduce the relevant precautions of china ph meter digital in detail:
1. Pay attention to circuit protection, short-circuit the input of the china ph meter digital when it is not working to avoid damage.
2. The glass electrode socket of china ph meter digital must be kept clean and dry at all times, absolutely avoid contact with harmful gases such as salt mist and acid mist, and it is strictly forbidden to get any aqueous solution on the glass electrode socket, which will cause high input impedance of china 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 containing 3mol/L potassium chloride solution.
