Urea Quality measurement can be performed with a sensor installed in the AdBlue tank or on the dosing line. In a demanding environment, such as the one met in off-highway applications, the in-tank measurement is particularly challenging as the physical properties are not homogeneous. However, in a tank, urea quality measurement can be achieved in a capable manner through a chemical analysis such as using a spectral absorption analysis.
