The 797 VA Computrace is a modern voltammetric measuring stand that is connected to a PC via a USB port. The computer software provided controls the measurement, records the measured data and evaluates it. Operation is most straightforward due to the well-laid-out structure of the program. The integrated potentiostat with galvanostat guarantees the highest sensitivity with reduced noise. Voltammetry system for the determination of organic additives in electroplating baths with ‘Cyclic Voltammetric Stripping’ (CVS). Complete accessories with VA Computrace software and all electrodes for a complete measurement system: Rotating platinum disk electrode (RDE), Ag/AgCl reference electrode and Pt auxiliary electrode.
