摘要

Electrochemical cell for continuous measurement of the sulphur dioxide content of air in the emission- and immision region has a diffusion electrode with an acid-soluble, reversible org. redox system as anode and a cathode contg. an active mass of which the redox potential is higher than the redox potential of the anode, together with a measurement cell contg. an immobilized electrolyte connected to a unit for measuring the short circuit current between the two electrodes. The instrument is portable and allows continuous monitoring of SO2 levels in the emission- and immision range.
