[Abstract]:
Before using the ph meter digital china, wash the electrode with distilled water. Be careful not to break the glass electrode.

1. Before using the ph meter digital china, wash the electrode with distilled water. Be careful not to break the glass electrode.

2. Prepare the NaOH solution and HCL solution for adjustment beside the platform ph meter digital china.

3. Take out the PH solution (PH=7.0) in the refrigerator and put it on the platform.

4. Open the ph meter digital china, set the PH value, press the ︿﹀ key to select the PH and CAL options, select the CAL item, adjust and insert it into the PH solution (PH=7.0), press the " " key to select the data value to 7.0 At the place, there is a small eight fork.

5. Insert the glass electrode into the solution to be tested, then put another electrode, and stir the liquid level properly (note: do not break the glass electrode).

6. The electronic unit of ph meter digital china must pay attention to the protection of the circuit. When the pH value is not measured, the input of the ph meter digital china should be short-circuited to avoid damage to the ph meter digital china.

7. The glass electrode socket of ph meter digital china must be kept clean, clean and dry, and should not come into contact with harmful gases such as salt mist and acid mist. At the same time, it is strictly forbidden to stain the glass electrode socket with any aqueous solution to avoid high input impedance of ph meter digital china. .
