ABSTRACT:
The present invention relates to a sensor apparatus configured to detect the presence of a gas, such as a tracer gas and a leak detection apparatus configured to detect the present of a tracer gas and indicate the location of a leak. The sensor apparatus includes multiple sensors, each of which is a metal halide sensor. The leak detection apparatus may further be configured to quantify the leak rate at the leak location.
