Product Introduction
CS300M Potentiostat/Galvanostat contains a fast digital function generator, high-speed data acquisition circuitry, a potentiostat and a galvanostat. With high performance in stability and accuracy with advanced hardware and well-functioned software, it is an entery and cost-effective model. With methods such as Potentiodynamic (Tafel plot), it’s widely used to measure pitting corrosion potential.
