Helium Leak Detectors
Helium leak detection is a very popular way to perform nondestructive testing. Helium leak detectors, which use helium as a search gas, are used to pinpoint the source of a leak. These leak detectors are utilized in many different products and industries, such as medical implant devices, automobile air bags, radiators, and air conditioners. Helium leak detection is common in industries including aerospace, automotive, industrial, hydrogen energy, medical and packaging, RAC/HVAC, utilities, and power.
After helium gas is pumped into the system and the leak is found, the helium leak detector can measure the rate of the leak. The leak rate is displayed in numeric and bar graph data on a touch screen. Helium leak detectors are available in automatic, semi-automatic, and manual testing systems.
Helium is used as a detector because it provides better test sensitivity and is inexpensive, inert, and lightweight. Helium leak detectors are most often used in steam turbine and condenser air in leakage testing, chemical and plastics production, heat exchangers, and underground pipelines.
