Product Introduction

  8-channel potentiostat/Galvanostat model CS3108 can achieve simultaneous measurements for up to 8 channels. The specifications of each channel are identical. Current control range is ±200mA, potential control range is ±10V. EIS 10μHz~1MHz is included in each channel. It supports floating mode, and uses Ethernet connection.
   Each channel is completely independent. so one set  8-channel potentiostat equals to that you have 8 set single-channel potentiostat.
  You choose to use just one or some of the channels. Multichannel potentiostat brings convenience to those who have many samples, and is an ideal device for studies of energy materials, battery study, metal corrosion etc.


High current/voltage: Applied potential range ±10V, current range ±200mA. It can meet the needs of most studies.
Comprehensive techniques: Built-in EIS (10μHz~1MHz) is equipped to one channel(CS3108). There are comprehensive techniques in each channel.
Warranty: 5 years warranty. We're the manufacturer, and our engineers will provide technical support anytime you need.
Low cost: The price includes instrument host, software(experiment control & data processing), necessary cables, dummy cell. No other charges. 
Reliability &quality: We've been in the market for 20 years, and now is the No. 1 brand of potentiostat product in China Application
-  Reaction mechanism of Electrosynthesis, electrodeposition (electroplating), anodic oxidation.
-  Electrochemical analysis, electro-catalysis, sensor; 
-  New energy materials, advanced functional materials, photoelectronic materials;
-  Corrosion study of metals in water, concrete and soil etc;
-  Fast evaluation of corrosion inhibitor, water stabilizer, coating and cathodic protection efficiency.
Simultaneous Measurements
The customer can choose a same electrochemical technique in every channel. For example, among 8 channels, you can choose to run 4 channels to all do EIS measurement. Set the parameters just one time, then EIS measurement in each channel will be conducted at the same time.

In each channel, you can also conduct different experiments.
As is shown in the below picture, EIS, galvanostatic charge and discharge, CV, and polarization curve tests are conducted at the same time.
