Online Electrochemical H2S Gas Analyzer can be used for
measurement of the concentration of H2S in sample gases simultaneously . It is
based on the fuel cell method (ECD) for H2S. This analyzer is designed with 19
inches 3U smaller physical dimensions .The general application is for CEMS application with 0-100ppm range.
