Use, maintenance and precautions

1. When the electrode is in use, the rubber stopper and rubber cap of the holes at the upper and lower ends of the electrode should be removed to prevent the diffusion potential from affecting the test results.

2. little salt bridge in the solution should be saturated to prevent the solution from short circuiting.

3. Rubber stopper and rubber cap must be used for electrode of double salt bridge. After proper inert electrolyte solution is filled into the second salt bridge solution, it can be used again to ensure the accuracy of test results.

4. When there is salt bridge solution or crystal on the electrode shell, it should be removed at any time.
