Abstract

A gas sensor assembly having a first housing portion having a receptacle formed therein and a second housing portion in the form of a cover. A gas-sensing agent is disposed in the receptacle, and a working electrode, a counter electrode, and a reference electrode provided on a single electrode support sheet are disposed in fluid contact with the gas-sensing agent. The first housing portion is provided with three conductive housing portions which are in electrical contact with the three electrodes, and the cover maintains pressurized contact between the three conductive housing portions and the three corresponding electrodes. The gas sensor may be provided with two different types of leakage detectors to sense leakage of the gas-sensing agent from the sensor.
