Pyroelectric detectors for NO2 measurements

27 July 2018

Laser Components is now offering its pyroelectric detectors with narrow-band IR filters for NO2 measuring (filter option V).

This makes the challenging NO2 measurement possible with non-dispersive infrared sensors (NDIR) – especially in combination with the company’s differential pyros. 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 process.

The concentration of carbon compounds has long been measured using NDIR. As a result different techniques were applied for each type of chemical compound.
