CH Instrument Electrochemical Workstation
The CH Instruments CHI600D Series Electrochemical Workstation is designed for general-purpose electrochemical measurements. It integrates a fast digital function generator, high-speed data acquisition circuitry, potentiostat, and galvanostat (in select models) to perform accurate and sensitive measurements, including currents down to picoamperes. This instrument is ideal for researchers conducting cyclic voltammetry, chronoamperometry, and other advanced electrochemical experiments.

Description
The CHI600D Series workstation provides high-precision control over potential and current for electrochemical experiments. Its 4-electrode configuration allows liquid/liquid interface measurements while minimizing connector resistance effects. Multiple data acquisition systems enable simultaneous recording of external signals such as spectroscopy. The instrument supports automatic zeroing of potential and current, true chronocoulometry integration, and fast scan rates up to 5000 V/s. With optional accessories like the CHI200B Picoamp Booster and Faraday Cage, currents as low as 1 pA can be measured reliably. Flash memory allows for rapid software updates, and the system supports both manual and automatic iR compensation, ensuring accurate and reproducible results for advanced electrochemical research.
