[0003] Currently, although there are many categories and quantities of devices for testing electrochemical electrodes, the existing test devices are generally complex and have deficiencies. The electrodes do not fully contact the electrolyte, which slows down the reaction effect. The anode and cathode are prone to shift, resulting in inconsistent anode-cathode spacing and inconsistent reaction areas of the electrode reactions. There may even be a short circuit caused by the contact between the anode and cathode. Summary of the Utility Model

[0011] The beneficial effects of the present utility model are as follows: Compared with the prior art, the electrochemical electrode immersion type testing device provided by the present utility model can fix the cathode and anode electrodes and ensure that the electrode distance does not shift by arranging electrode card slots inside the electrolytic cell body, with reasonable design and simple operation; the electrode conductive joints are fixed through the cell body openings, which is convenient for installation and can ensure high conductivity during the electrode testing process; by leaving voids on both sides of the electrolytic cell body, it can ensure that the electrodes are fully immersed in the liquid and improve the testing accuracy.
