CS100 Portable Electrochemical Analyzer

Introduction

The CS100 portable electrochemical analyzer communicates with the computer using an optically isolated USB 2.0 interface and can be powered directly from the USB port without the need for an external power supply. The circuit uses a floating design that measures the electrochemical parameters of the grounding system without the need for an isolation transformer. The device is easy to install and plug and play. With excellent stability and precision, advanced hardware and well-functioning software, it provides an excellent research platform for scientists involved in energy, materials, life sciences and environmental protection.
