Nox sensors are commonly used in pairs on three-way catalytic converter. It's installed before DOC chamber and after SCR chamber to detect Nox contents level. TB offers OEM quality Nox sensors for replacements or repairs.
Nox particle level is measured with Nox sensors' special inner ceramic structure which made of ZrO2. The ceramic is often plated with platinum to create a voltage difference between the exhaust gas and atmosphere air due to the Oxygen percentage difference
