Helium Leak Detector also known as the Mass Spectrometer Leak Detector MSLD is used to find the location and measure the leakage rate of a system. A helium mass spectrometer is an instrument commonly used to detect and locate small leaks. It was initially developed in the Manhattan Project during World War II to find extremely small leaks

If a leak is present helium comes out and is sucked in to the sniffer probe and through that to the leak detectors mass spectrometer. The leak rate meter will show a display of the signal. When the maximum leak rate display is found the leak is located. This method has two advantages and two disadvantages compared to the vacuum method
