Detectors with IR Filters for NO₂ Measuring

LASER COMPONENTS is the first manufacturer to offer its pyroelectric detectors with narrow-band IR filters for NO₂ measuring (filter option V). This innovative change makes the challenging NO₂ measurement possible with non-dispersive infrared sensors (NDIR) - especially in combination with the
company’s differential pyros. Manufacturers of exhaust gas measurement systems will now be able to expand their devices by an additional IR measuring channel.

Up until now, 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.

With these new NO₂ filters, LASER COMPONENTS strengthens its position as the IR detector manufacturer with the widest standard range of bandpass filters.
