Three, use and precautions

1When the reference 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

2And not in the electrode solution saltbridge bubble solution to prevent short circuit, electrode saturation models should retain a solution of salt crystals, to ensure saturation requirements.

3Electrode, double salt bridge, we must remove the rubber plug and the rubber cap, the second section saltbridge loaded with appropriate inert electrolyte solution, and then loaded on the use, in order to ensure accuracy of test results.

4And when the electrode shell with salt bridge solution or crystallization, application of distilled water, so as not to bring into the tested solution that affect the measurement accuracy
