Pine Item #54371
The Model 42C High Level (42-HL) combines the superior optical, mechanical, and chemical characteristics of its predecessor, the Model 42H, with an enhanced electronics package and user interface. The outcome is a powerful, easy-to-use, chemiluminescent based analyzer capable of measuring oxides of nitrogen from parts per billion (ppb) to 5000parts per million (ppm). Using Chemiluminescence, the 42C series is capable to measuring oxides of nitrogen from sub parts per billion (ppb) to 5,000 parts per million (ppm). Extended troubleshooting diagnostics provide instantanuous indication of instrument operating status.
