Introduction of Helium Leak Detector:
Helium leak detectors are used to detect and locate leaks in various systems, including vacuum systems, refrigeration systems, and pipelines. They work on the principle of mass spectrometry, which involves ionizing helium atoms and measuring their mass-to-charge ratio to detect the presence of leaks.

Applications of Helium Leak Detector:
Helium leak detectors are used in a variety of applications, including vacuum systems, refrigeration and air conditioning systems, and research and development. They are particularly useful for detecting small leaks that would be difficult to locate using other methods. Helium is also non-toxic, non-flammable, and does not react with other substances, making it a safe and clean tracer gas for leak detection.
