ABSTRACT:
An electrode structure for a halogen leak detector is disclosed in which the cathode portion is provided with a hollow metal tube through which air or other cooling fluid is passed. This hollow metal tube may also serve as the cathode electrical connection and for mechanical support. Since halogen leak detector systems are typically provided with air pumps for the passage of ambient air through the detector, it is a simple matter to also pass a stream of ambient air through the hollow metal tube in the cathode in order to maintain the cathode at a lower and more controlled temperature, thereby increasing the sensitivity of the detector and prolonging its useful life.
