The i-series gas analysis instruments represent the latest technology in the industry. Our users have told us that their ideal gas monitoring system should be stable, simple, and easy to use. The new i-series instruments not only have the above characteristics, but also have even better performance. The 42i NO-NO2-NOx analyzer is a representative product among them.

The 42i NO-NO2-NOx analyzer combines the excellent optical, mechanical, and chemical properties of the previous generation 42 analyzer, adds network interfaces, and improves circuit design and user interface. The instrument uses chemiluminescence to analyze the concentration of nitrogen oxides, which is reliable and effective. Its analytical ability for nitrogen oxides can range from sub ppb to 100ppm. The 42i NO-NO2-NOx analyzer adopts a single reaction chamber and single photoelectric amplifier design, and switches between NO mode and NOx mode through an electromagnetic valve.

The 42i NO-NO2-NOx analyzer can simultaneously output the concentrations of NO, NO2, and NOx, and can independently calibrate each gas escape. The instrument can also be set to dual range or automatic range working mode. If necessary, the instrument can be set to NO or NOx continuous detection mode with a response time of less than 5 seconds.

The 42i NO-NO2-NOx analyzer has temperature and pressure correction functions. Users can set concentration alarm values and other parameter alarm values for internal diagnosis.

The analyzer has network functionality, and increasing the memory can store more data. The newly added network interface makes remote control more convenient, allowing users to download monitoring information remotely. The newly added 'soft key' function allows users to set the function of the keys according to their needs, thereby directly entering commonly used menus and functions. The enlarged LCD screen can accommodate more information, and in addition to always displaying analysis results, it can also simultaneously display other operation menus, operating status, and other information.
