Oxygen Sensor Gas Compatibility

Analysers and sensors based on the galvanic principle are suitable for the measurement of oxygen ranging from 100 PPB to 100% in a variety of background gases in a wide range of applications. It is important to establish the compatibility of the galvanic oxygen sensor in the background gas of each application. This table is designed to assist you in selecting the correct sensor.
