Product Introduction
Corrtest Multichannel potentiostat/ galvanostat/EIS is a versatile instrument offering 8 slots.
Full floating module and electrical isolation design guarantee each channel is totally independent, which ensures accurate data and efficient simultaneous measurements.
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.
Number of channels can be customized. Different configuration ensures you get desired product
suiting to various budgets


 


The number of channels is expandable by adding and installing more boards, thanks to the intelligent chassis and plug-in design. Each channel potential control range is10V, current control range ±1A, can meet experiment requirement for most people.

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.


Advantages
High current/voltage: Applied potential range ±10V, current ±1A. It can meet the needs of most studies.
Comprehensive techniques: Built-in EIS (10μHz~1MHz) is equipped. 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


Simultaneous Measurements
You can run a same experiment for each channel at the same time. Set the same parameters for each experiment once and run all independently. It's especially useful when you have many samples for one single test.

You can also choose different techniques in each channel. Set the parameters for each
experiment one by one, and run each experiment independently. As is shown in right picture, EIS, Galvanostatic charge & discharge, Cyclic Voltammetry, and polarization curve test are tested.
