According to LASER COMPONENTS, it is the first manufacturer to offer its pyroelectric detectors with narrow-band IR filters for NO2 measuring (filter option V). This makes NO2 measurement possible with non-dispersive infrared sensors (NDIR). Manufacturers of exhaust gas measurement systems will now be able to expand their devices by an additional IR measuring channel.
Traditionally, the amount of NO2 in exhaust gases has been determined by UV or electrochemical methods. Engine development was the only field using laser-based IR processes. The concentration of carbon compounds, on the other hand, has long been measured using NDIR. As a result, different techniques were applied for each type of chemical compound.
