Abstract
A probe is conveniently positioned in a flowing aqueous medium. The probe is formed by two electrodes of notable difference in nobility connected by an electric resistance high enough to ensure that the voltage difference between its terminals is sufficiently great to permit accurate and simultaneous determinations of the growth of biofouling and the chlorine concentration by measuring the potential difference variations between the terminals.
