COSO | Environmental gas analyzers for trace analysis of SO₂, O₃ & NO_x

LFE developed the COSO series of trace gas analyzers for SO₂, O₃ and NO_x in cooperation with the German Weather Service (Deutscher Wetterdienst). These analyzers utilized electrochemical cells which were highly sensitive to trace concentrations of the chosen components. The COSO series with its requirements for various chemicals was unfortunately not as attractive for customers as analyzers employing physical detectors and was therefore discontinued in 1988.
