Product Introduction
CS3104 multichannel Potentiostat Galvanostat can achieve simultaneous measurements for up to 4 channels.
There are other 4 slots without boards. You can add potentiostat/galvanostat board in the future if you have the need.We just need to ship the board to you for channel expansion. 
For each channel, current control range is ±1A, potential control range is ±10V. It supports floating mode, and uses Ethernet connection. Each channel is completely independent. Multichannel potentiostat brings convenience to those who have many samples, and is an ideal device for studies of energy materials, metal corrosion etc.
 EIS module (10μHz~1MHz) is equipped one channel.



(1) Reaction mechanism of Electrosynthesis, electrodeposition (electroplating), anodic oxidation, etc.
(2) Electrochemical analysis and sensor; 
(3) New energy materials, advanced functional materials, photoelectronic materials;
(4) Corrosion study of metals in water, concrete and soil etc;
(5) Fast evaluation of corrosion inhibitor, water stabilizer, coating and cathodic protection efficiency.
