Single Channel Potentiostat Galvanostat
Single channel potentiostat galvanostat consists of DDS arbitrary function generator, high power potentiostat/galvanostat, dual-channel correlation analyzer, dual-channel high-speed 16bit/high-precision 24bit AD converter and extension interfaces. Max. current is ±2A, potential range is ±10V. EIS frequency range is 10uHz~1MHz. Single channel potentiostat galvanostat can be used for various electrochemical fields such as corrosion, energy, material and electroanalysis. The current can be boosted up to 20A/40A when a Single channel potentiostat galvanostat is connected with a current booster CS2020B/ CS2040B. There are 3 models among single channel potentiostat galvanostat. CS350M is the most advanced single channel potentiostat galvanostat with EIS. Model CS310M also includes EIS but has less voltammetry technique. Model CS300M is the entry single channel potentiostat galvanostat model without EIS.
