The Thermo 42i Analyzer combines superior optical, mechanical and chemical characterisitics. The outcome is a powerful, easy-to-use, chemiluminescence based analyzer capable of measuring oxides of nitrogen from sub parts per billion (ppb) to 100 parts per million (ppm). Extended troubleshooting diagnostics provide instantaneous indication of instrument operating status. Used in souce emissions monitoring as well as ambient air monitoring.
