| 摘要 |
The present disclosure relates to a sensor apparatus (300, 300', 300", 450) configured to detect the presence of a gas, such as a tracer gas and a leak detection apparatus (100, 100') configured to detect the presence of a tracer gas and indicate the location of a leak. The leak detection apparatus (100, 100') may further be configured to quantify the leak rate at the leak location.
