Pfeiffer Vacuum HLT Helium Leak Detectors are well-known and widely recognized throughout the market of leak detection, and are proven to be among the most effective products in the helium leak detector market.
Leak detection utilizing helium has a complex history dating back to the first half of the twentieth century and is used in a variety of processes and industries. Helium is used as the preferred tracer gas for eliminating leaks for a variety of reasons, including its non-flammability, non-toxicity, and inexpensiveness relative to other gases. Likewise, its inert state and small atomic size (helium has an atomic mass unit of 4 - second only to hydrogen, which has an AMU of 2) allows the gas to pass through leaks with ease. Unlike hydrogen however, helium is stable and non-explosive, providing a better alternative to be used in leak detection processes.
Utilizing the beneficial qualities of helium, a Helium Leak Detector pumps molecules of the gas into the device's analyzer cell through the use of vacuum pumps. The analyzer cell works on the principle of mass spectroscopy and measures the gas's partial pressure, displayed on the device's spectrometer. A higher reading indicates that a leak may be present, as represented by the quantity and concentration of helium molecules that have passed through a given space, as analyzed by the device. The leak detector converts this partial pressure of molecules into a flow rate. Helium leak detectors are known to be extremely precise and exhibit unparalleled accuracy in detecting leaks.
