VS Series Helium Mass Spectrometer Leak is a wide range of sophisticated helium leak detectors, which contain high turbo molecular pump, built-in mechanical pump, an external mechanical pump, spectrometer tube, valve, leak detector electronics and operator interface, and optional functional components. VS MR15x and VS MD30x model leak can choose two-wheeled vehicle. All models are suitable for leak 100/115 VAC and 230 VAC.
Features:
• Multilingual and measurement units selection, optional Chinese interface
• 135 º ionization deflection (natural focal point) of a new mass spectrometry technology, metal seal structure
• New design of electronic circuits and signal processing
• Minimum leak rate, the sensitivity of the coverage range up to 12
• Quick clean helium and fast response
• High pressure test port, enabling large leak leak
