continuous oxygen concentration measurement for compatible catalytic converter exhaust testing applications.<\/p><p>Connected to appropriately designed exhaust gas sampling and conditioning systems, the OMD-190 can monitor oxygen concentrations upstream or downstream of a catalytic converter. Separate analyzers allow simultaneous measurements at both locations, while an engineered sample-switching system can support sequential measurements using a single analyzer.<\/p><p>When integrated with compatible test cell data acquisition systems, oxygen measurements can be recorded alongside other exhaust gas parameters to support catalyst development, oxygen storage characterization, and emissions performance evaluation.<\/p><p>Proper sample conditioning, gas compatibility, and consistent sampling conditions are essential for reliable results.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-91e1787 elementor-icon-list--layout-inline elementor-align-start
