Thermo Fisher Scientific - Model 42i TL -Trace Level NOx Analyzer
Using chemiluminescence technology, the Model 42i-TL measures the amount of nitrogen oxides in the air from sub-ppb levels up to 1000ppb. 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 has independent outputs for NO, NO2 and NOx and each can be calibrated independently.
Temperature and preasure correction are standard features. User settable alarm levels for concentration and for a wide variety of internal diagnostics are available from an easy to follow menu structure.
This state of the art gas analyzer offers features such as an Ethernet port as well as flash memory for increased data storage and field upgradeability.
Ethernet connectivity provides efficient remote access, allowing the user to download measurement information directly from the instrument without having to be on-site.
You can easily program soft keys to allow you to jump directly to frequently accessed functions, menus or screens. The larger interface screen can display measurement information and status, while viewing menu and operational screens
