Measure levels of nitrogen oxide (NO-NO2-NOx) in the emissions from a source using chemiluminescent technology with the Thermo Scientific™ Model 42i NO-NO2-NOx Analyzer.
Improved layout for easier accessibility to components
The Model 42i NO-NO2-NOx Analyzer is also available with an oxygen sensor module.
Using paramagnetic sensor technology the Model 42i with Oxygen gives the source measurement of NOx extended capabilities to read and report the concentration of oxygen in the sample stream up to 100%. Additionally, programming allows the user to correct the NO, NO2, and NOx reading for the amount of oxygen in the sample.
