The paper deals with the construction of a simple electronic equipment made from commercially available components, suitable for recording alternately the potential and the current data for a polarographic curve on a five-track perforated tape. The apparatus can operate in three modes making it possible either to record the polarographic curve or the current as a function of the time at constant polarization potential or the current-time curves on individual drops.
