AdBlue / DEF / Urea Quality Sensor

Continuous sensing of Urea Quality and Urea concentration in DEF / AdBlue® / UREA aqueous solution.
Using special optical techniques, AB Elektronik’s sensor is capable of
detecting variances in urea concentration as small as +/- 2 %, and can operate at temperatures from -10 degC to +85 degC.
The optical measurement principle is robust against dirt and moving fluids including gasoline, diesel or coolant.
