O2 Sensor

HIRIH ZIRCONIA 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.

The basic element is a thimble-shaped section of electrolyte (Zirconium Oxide), which is called zirconium tube, flanked by a pair of thin micro porous platinum electrodes on both sides. The inner electrode is exposed to the atmosphere, while the outer electrode is exposed to the exhaust gas. It has some characters when meeting with high temperature: since the atmosphere side of the electrolyte is exposed to a higher concentration of ions than the exhaust side, the inner electrode becomes negative with respect to the outer electrode.

Oxygen ions are able to pass through the element and deposit a charge on the platinum electrode thus generating the voltage signal when the big difference for concentration exists. 

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.

3) HIRIH oxygen sensors are with fast reaction, high performance properties, that are even   better than OE equipment.

4) Fits a HIRIH oxygen sensor, you will get:

a) Improved fuel economy

b) Lower exhaust emission

c) Better engine performance

5) We both supply universal oxygen sensors and direct fit oxygen sensors with connectors

6) Applied for around 20,000 different OE part numbers.
