From the manufacturer:

Measure the amount of nitrogen oxides in the air from sub-ppb levels up to 1000 ppb using chemiluminescence with the Thermo Scientific™ Model 42i-TL TRACE Level NOx Analyzer. The Model 42i-TL is a single chamber, single photomultiplier tube design that cycles between the NO, NOx, and Zero modes. The addition of the Zero mode provides for excellent long term stability and extremely low minimum detectable limits. The 42i-TL has independent outputs for NO, NO2, and NOx and each can be calibrated independently.
