High precision electronics helium mass spectrometer leak detector Product Description:

 
Helium Mass Spectrometer Leak Detector refers to as a diagram with helium or hydrogen gas leak, a gas analyzer helium mass spectrometer leak. The low noise floor of helium, small molecular weight and viscosity coefficient, and therefore easy to spread easily through the drain hole; In addition, the inert gas helium-based, non-corrosive, it is commonly used as shown helium gas leak. This gas will then have to spray the gas analyzer (adjusted only for helium from the operating state of the reaction) was seized container, if the container tainted holes, namely the analyzer to react, so we can see where the leak and drain volume size.
 
High precision electronics helium mass spectrometer leak detector Leak detection principle:
 
Helium leak vacuum leak detection technology is indispensable to a field of technology, due to the high efficiency of leak detection, simple and easy to operate, the instrument responsive, high precision, easy to interference by other gases, has been in the resistance furnace leak detection widely used. Helium leak detectors are based on the principle of mass spectrometry, as shown with helium leak into the system leak testing equipment. By mass spectrometry chamber and exhaust systems and electrical parts from the ion source, analyzer, collector, cold cathode gauges and other components of. MS room filament emitted electrons oscillate back and forth in the room, and the indoor gas leak through the hole and into the interior of the helium collision ionizing positive ions, helium ions into the magnetic field in the accelerating electric field, Since the Lorentz force generated by the deflection, a circular arc-shaped track, can change the accelerating voltage of ions of different mass through a magnetic field and receiving slits reach the receiving electrode is detected. Helium spray method, a method is sucked helium mass spectrometer leak in the helium leak resistance furnace in the two most commonly used methods.
 
High precision electronics helium mass spectrometer leak detector Application:
 
Helium leak detector is also named Helium Mass Spectrometer Leak Detector, it is widely used in aerospace, scientific research, power industry, large-scale production line, valve industry.
 
We offer a wide range of customized solutions for vacuum coatings, scientific research, lighting, solar energy, analytical instruments, electronics and semiconductors, and other industries.
