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.
