Oxygen Sensor

HIRIH manufactures zirconia sensor, which has the precise craftwork, stable performance, particularly we have mastered the technology and development for the high sensitive ceramic coating.

Our capable engineering team together with advanced diagnostic and testing equipments enable us to offer products with high quality to our clients.

Function of Oxygen Sensor:

The oxygen sensor monitors the engines air to fuel ratio by measuring the amount of free oxygen in the exhaust. It reports this information to the engine control unit or ECU. Approximately every 10 milliseconds the ECU uses this information to make corrections to the air to fuel mixture for maximum efficiency.

HIRIH Oxygen Sensor Features:

1) Designed and made to be outstanding performance and manufactured to meet or exceed original equipment specifications.

2) Each component is made to be an exact replacement and a direct fit.
