The CS100ME 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. CS100ME can be a convenient handheld tool for researchers of energy& materials, environment protection, biosensor, foods &drugs, corrosion protection etc. Maximum current is ±100mA

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

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.

Features

- Small & light, handheld and convenient

- Easy to install and use

- High accuracy, current resolution can reach to 1pA, 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.
