Some usage methods of ph meter digital
1) Before using the ph meter digital, first use triple distilled water to clean the electrode, and also pay attention to the glass electrode not to be broken.
2) Put the NAOH solution and HCL solution for adjustment next to the ph meter digital on the platform. Take out the fixed pH solution (PH=7.0) in the refrigerator and put it on the platform.
3) Turn on the ph meter digital, adjust the PH value, select the PH and CAL options, select the CAL item, adjust and insert it into the PH solution (PH=7.0), and select the data value to 7.0.
4) Place the glass electrode in the solution to be detected, and stir properly.
5) The electronic unit of the ph meter digital must pay attention to the protection of the circuit. When the pH value is not measured, the input of the ph meter digital should be short-circuited to avoid damage to the ph meter digital.
