Automotive exhaust gas analysis

Low emission means low ranges
Combustion engines emit a large number of gaseous substances that must be limited according to national and international regulations (e.g. EURO6). The control is carried out with appropriate exhaust gas analyzers. For this application, Wi.Tec offers carbon monoxide (CO), carbon dioxide (CO2), hydrocarbon (HC), nitrogen oxide (N2O) sensors and NOx modules that comply with the latest technology and standards.

The INFRA.sens® CO2 / N2O / CH4– AK5 / AK220G is based on the EURO7 standard, which is currently under discussion. The measurement of carbon dioxide is performed up to 20 Vol.%, the measurement of nitrous oxide and methane is performed in the lower ppm range. Here, all cross-sensitivities of the gases to each other are already calculated in the main electronics and a cross-sensitivity to carbon monoxide can be excluded.
