The Helium Leak Detector Helium Leak Detector Main Components The main components of a helium leak detector are: 1. The analyzed, which enables to separate the tracer gas from ... helium mass spectrometer. This in contrast to a vacuum decay processes where the pump source is valved off to observe a pressure variation.
The Mass Spectrometer Leak Detector is a complete system for localization and measuring of leaks inside or outside of a product. This method uses so called tracer gas – helium, which is used to fill up the product connected to the detector.

Helium Leak Detectors PTB has over a decade of experience in refurbishment and sales of portable mass spectrometer helium leak detectors and now offers helium leak detector rentals in partnership with Agilent Technologies (Varian Vacuum acquired by Agilent).
Helium Leak Detectors The PHD4 is able to detect very small leaks in objects that have a slight helium/air pressure inside. It is sensitive to helium concentrations as small as 2 ppm equivalent to a leak rate of 5 x 106 atmcc/sec, far superior to the performance by other means of detecting leaks, such as bubbletesting.
The helium mass spectrometer is used to measure the helium that is sprayed around each joint being tested.. If there is a leak in the product allowing helium to enter (outsidein leak), the flow rate in the chamber changes and is detected by the mass spectrometer.
The PCU Helium Mass Spectrometer Leak Test System is a compact easy to operate ultra fine leak test system. This system embodies PCU's field proven testing technology in combination with modern electronic control, compact industrial design and simplified operator use.

In most helium leak testing a pplications, one uses a m ass spectrometer (leak detector) tuned to detect helium. A 95% nitrogen 5% hydrogen mix can be used as .
Helium Leak Test Systems For leak testing applications that have a reject leak rate too small to accurately detect with air leak testing instruments, your best choice for measurable and repeatable leak testing results is with Helium leak testing.
Helium leakdetection is possible owing to the lightness of the gas and its concomitant small molecular size, allowing detection of even the smallest hole or tear. The leaking helium is detected by a simple and conventional mass spectrometer that is designed to detect only helium gas.
