NOx Sensor 5WK9 7401

NOx sensor 5wk9 7401 is a part of the NOx reduction after-treatment system in diesel vehicles using a urea-based SCR system. In the 5wk9 7401 NOx sensor, NOx is separated into nitrogen and oxygen by a catalytic active electrode. NOx sensor 5wk9 7401 can measure and emit NOx at the same time, and can quickly and accurately detect the NOx concentration level in the gas.
