Ceradex Corporation was established in 1999 and specializes in manufacturing Oxygen Sensors in Taiwan. We invested large amounts of fund in researching and developing Oxygen Sensors. In fact, we had started developing the technology of Oxygen Sensor ever since 1990. Therefore, we have a lot of experiences in this area. These experiences include developing the necessary material (stabilized YSZ powder) in house with our own formula for ceramic element and functions. Under such condition, we are able to manufacture Oxygen Sensors with stable and good quality. This is something that we are very proud of! In Ceradex, our mission is to provide our customers with excellent services and superior quality products.
