CST520 Array Electrode Electrochemical Scanning System
Introduction: The CST520 array electrode electrochemical scanning system consists of two parts: the array electrode extension module and the electrochemical test module. It can not only realize the electrode potential and short-circuit current test of any single electrode, but also measure the AC impedance of each single electrode and The polarization curve data greatly enriches the corrosion resistance evaluation methods of materials. The CST520 array electrode electrochemical scanning system can accurately measure the electrode potential of any single electrode and the current of the short-circuit galvanic cell, without worrying that the external polarization may destroy the micro-corrosion environment, so it is especially suitable for the study of spontaneous corrosion behavior of metals in an undisturbed state . working principle: The CST520 array electrode electrochemical scanning system consists of two parts: the array electrode extension module and the electrochemical test module.

The array electrode expansion module is mainly composed of RS485 communication circuit, IO expansion circuit, 10x10 relay matrix circuit, MCU circuit and so on. Two expansion board interfaces are reserved to support up to 300-channel array electrode switching, and the switching rate can reach up to 100Hz. The standard version is 100 channels, the array electrodes are input through 2 DB50 interfaces, the electrochemical workstation and the instrument are connected through DB9 connectors, and RS485 is used for communication between the two, and the communication rate is 115200bps. In addition to the array electrode fitting test, the electrochemical test module can also be used as an independent electrochemical workstation, with commonly used electrochemical corrosion test functions, including: open circuit potential test (OCP), polarization curve test (Tafel), linear electrode test Chemical test (LPR), AC impedance test (EIS), Mott-Schottky curve test (M-S) and electrochemical noise test (EN) and other functions.
