Model R-17A Oxygen Sensor


Teledyne has a long and successful history in the development and supply of oxygen sensors for automotive emission testing equipment.​

The “R” series sensors are used by most automotive emission equipment manufacturers worldwide. We are striving to improve our sensors through aggressive research and development, assuring the highest quality products offered by any supplier of oxygen analyzers.




Resistance to CO2

Recent major breakthroughs by Teledyne include the utilization​ of a special plating on the cathode resulting in a 200 times greater resistance to the effects of CO2. This increases the useful life of the sensor when used in exhaust emission testing.

Because of this innovation, the field failure rate for  Teledyne sensors has diminished to less than 1%  over the last year for hundreds of thousands of sensors shipped annually. From our clients’ perspective, there are far fewer field service calls due to the oxygen sensor not functioning properly.

Teledyne is committed to maintaining competitive pricing to assure our clients benefit from the most advanced design in oxygen sensors. To demonstrate the quality of Teledyne’s oxygen sensors, we have certification from the Bureau of Automotive Repairs for BAR97, BAR90, and the PTB as a stand alone component.  ​

The response of the sensors meets or exceeds the required time response, and the quality and reliability of the sensors are beyond standard requirements.  In addition, Teledyne is an ISO-9001 certified quality management system ​company, dedicated to quality, performance and customer satisfaction.​
