Two,218Silver-Silver chloride electrodeMaintenance and precautions

When the 1 electrode is in use, the rubber plug and the rubber cap at the upper end and the lower end of the electrode should be pulled out to prevent the influence of the diffusion potential on the test result.

There are no air bubbles inside the electrode in the solution of 2 salt solution, to prevent short circuit, electrode saturation models should retain a solution of salt crystals, to ensure saturation requirements.

The 3 electrode double salt bridge, in use must be the rubber plug and the rubber cap, second salt solution into the appropriate inert electrolyte solution, and then loaded on the use, in order to ensure accuracy of test results.

When the 4 electrode shell pay salt bridge solution or crystallization, should be removed at any time.
