Helium and/or hydrogen leak detectors

Main equipment:

The leak detection technique by Helium and / or hydrogen leak allows to measure and locate the smallest leaks. They are very sensitive techniques (hundredths of a gram of gas per century!).

The technique consists in producing a pressure difference between the walls of the part (whose tightness must be verified), generating vacuum on one side and / or exerting high pressure on the other side. If there is a leak in the wall, the very light Helium molecules will pass through it, thanks to the pressure difference. With a mass spectrometer integrated into the detector, helium flow is measured at the applied pressure difference. The amount of the leak is measured in mbar x l / s or grams per year.

Pfeiffer Vacuum is the world leader in helium leak leak detectors with over 10,000 units in use worldwide, in industries such as automotive, aerospace, home appliances, electronics, metal-mechanics and research centers. Their equipment is recognized as being of the highest sensitivity, very robust and easy to maintain in the field. AVACO has specialists in the application of this technique and can assist you in choosing the appropriate method and detector.

Types of He and H2 Leak Detectors

  • Portátil, modulares (para fácil e eficiente integração);
  • Para trabalhar em modo cheirador (sniffing) (com pressão de Hélio ou Hidrogênio), modo vácuo ou ambos;
  • Do tipo convencional com bombas a óleo, ou secas para eliminar os riscos de contaminação.
