Product Description

The CS100E handheld potentiostat supports full electrochemical methods, including potentiostatic/galvanostatic polarization curve, Cyclic voltammetry analysis, impedance(EIS), and galvanic current measurement. etc. It has built-in chargeable li-ion battery and Bluetooth communication. The device supports laptop/computer software or mobile APP.  It can be used for electrochemical tests in field or special non-electricity environment. CS100E can be a convenient handheld tool for researchers of energy& materials, environment protection, biosensor, foods &drugs, corrosion protection etc. Maximum current is ±45mA

The voltage control range is ±10V, compliance voltage is ±12V, the maximum current output is ±45mA, and the minimum current resolution can reach 100fA. The EIS frequency range is 10μHz~1MHz.

Features
- Small & light, handheld and convenient
- Easy to install and use
- High accuracy, current resolution can reach to 100fA, and measurement accuracy is 0.1% of the range.
-during outdoor test, a laptop's USB port can be used for both charging and communicating
- The circuit adopts floating design. Electrochemical parameters of the grounded system can be measured without an isolation transformer.

Thanks to its small size with comprehensive electrochemical functions, it's typically used for:
- Battery materials' performance test in a glove box
- Ultra-low detection limit of heavy metal ions for water quality test in environmental protection field
- Low current detection in biosensor thanks to high current accuracy  
- Effective ingredients detection in food and drug industry  
- Outdoor bridge corrosion and soil corrosion measurements
Note: maximum current during experiment doesn't exceed ±45mA then the handheld potentiostat can be used. If exceeds ±45mA an ordinary size potentiostat with maximum current ±2A should be considered.

   
  The CS100E portable can be controlled by either our desktop software or App.

Applications
Corrosion Electrochemistry
CS potentiostats /galvanostats support a variety of electrochemical techniques for corrosion, such as OCP recorder, potentiodynamic, EIS, cyclic polarization (CPP), LPR, hydrogen diffusion test, zero resistance ammeter (ZRA), electrochemical noise (ECN), etc.
Due to their high input impedance(10¹³Ω), they are especially suitable for EIS measurement of high-impedance systems like coating, concrete, and pure water.
