Nanao Oxygen Sensor
Emission & Engine Control Sensors
The Nanao O₂ Sensor (Oxygen or Lambda Sensor) is designed to accurately measure the
oxygen concentration in the exhaust gases of internal combustion engines. By providing realtime feedback to the Engine Control Unit (ECU), it ensures the optimal air-fuel ratio (λ = 1)
for efficient combustion, reduced fuel consumption, and minimal emissions.
Built with high-performance zirconia or titania elements, the Nanao O₂ Sensor guarantees
long-term stability and precision under demanding exhaust conditions.
