ELECTROCHEMICAL TESTING DEVICE

原文（中国語）

The present disclosure provides an electrochemical testing device, including: a working platform mounted with a mechanical arm, a test piece tray, a cup cover bracket and an electrochemical testing assembly. The electrochemical testing assembly includes a solution cup including a liquid through hole at a bottom, a reference electrode, an auxiliary electrode, a working electrode test piece, a test piece pallet and a columnar copper wire. The columnar copper wire lifts up the working electrode test piece to press and seal it on the liquid through hole. A cup cover of the solution cup is on the cup cover bracket, attached with the reference electrode and the auxiliary electrode. The mechanical arm injects and suctions a test solution, and transfers the working electrode test piece between the test piece tray and the test piece pallet and/or transfers the cup cover between the cup cover bracket and the solution cup.
