Product description :
Use of pH meter buffer solution:250mL of buffer solution can be used multiple times, and the amount of buffer solution used for the ph meter can be as long as it can completely submerge the glass electrode. Used pH meter buffer should be emptied and not reused. And the remaining portion store in a cool and dry place at 20-25 ℃. After using it for a period of time, the electrode of the ph meter will be asymmetric, and the potential will undergo significant changes, so regular calibration is necessary. |
