For Clean Air

US41-087

Particularly since the diesel scandal, everyone has been talking about the concentration of nitrogen dioxide in the air. While carbon compounds are routinely measured using the NDIR method, the search for standard IR detectors with filters for NO₂ measurements has been pursued in vain. To detect nitrogen oxides, usually electrochemical or UV processes are used. In engine development, laser-based IR processes are employed.

LASER COMPONENTS has established itself in recent years as the manufacturer of pyroelectric detectors with the broadest range of standard bandpass filters. It is therefore only logical to expand this leading product range: We now offer pyroelectric detectors with narrow-band IR filters for NO2 measurement (filter option V) upon request. The filter specifications were developed in close cooperation with users.

This makes it possible for manufacturers of NDIR exhaust gas measuring benches to expand their devices by an additional IR measuring channel and to dispense with alternative methods. Two further innovations from LASER COMPONENTS are very helpful in this context: Firstly, the gas humidity can also be measured using NDIR with the help of the “M” filter. Secondly, NO₂ measurement is without a doubt challenging and we therefore recommend the use of the latest and best detector generation – our differential pyroelectric detectors.
