Nox Sensor

A Nox (Nitrogen Oxide) Sensor measures the concentration of nitrogen oxides (NO and NO₂) in the exhaust gases of diesel and gasoline engines. It plays a critical role in emission control systems by providing real-time data to the Engine Control Unit (ECU), helping to optimize fuel injection and exhaust treatment systems such as SCR and EGR.

Nox Sensors are essential for reducing harmful emissions in vehicles such as trucks, buses, passenger cars, and industrial engines, ensuring compliance with environmental regulations.
