Description

EIS potentiostat CS310M consists of DDS arbitrary function generator, high power potentiostat and galvanostat, EIS/FRA module, dual-channel correlation analyzer, dual-channel high-speed 16bit/high-precision 24bit AD converter and extension interfaces. Max. current is ±2A, potential range is ±10V. Compliance voltage is ±21V. EIS frequency range is 10uHz~1MHz. Equipped with EIS techniques, EIS potentiostat CS310M can be used for various electrochemical fields such as corrosion, energy, material, electroanalysis, sensor, electrodeposition etc. The current can be boosted up to 20A/40A with a current booster CS2020B/ CS2040B. Compared with EIS potentiostat model CS350M which is the most advanced single-channel potentiostat galvanostat, CS310M has less voltammetric techniques.

What is a potentiostat?

A potentiostat is an analytical instrument that controls the voltage difference between a working eectrode(WE) and a reference electrode(RE). In almost all applications, the potentiostat measures the current flow between the working and counter electrodes. The controlled variable in a potentiostat is the cell potential and the measured variable is the cell current. When we say potentiostat, it’s also galvanostat or electrochemical workstation. It consists of a potentiostat that controls the voltage across an electrochemical cell, and a galvanostat that controls the current through the cell. It is widely used to study electrochemical reactions in corrosion, electrodeposition, battery testing, sensor, eletrocatalysis etc.
