NH 400 Wet Helium Leak Detector
NH 400, One of the Best Helium Leak Detectors from China
Smallest Detectable Leak Rate: 3×10-13 Pa · m3/s
Equipped with Pfeiffer/Leybold/Inficon
NH 400, one of the best leak detectors from China, represents a state-of-the-art, fully automated mobile helium mass spectrometer system designed to meet the stringent requirements of a diverse range of industries.
Distinctive gas path design ensures that no dust infiltrates the instrument.
Versatile multi-mode input and output functionality facilitates seamless integration with a wide range of automation equipment.
Equipped with a dual iridium filament ion source, offering exceptional oxidation resistance and an extended operational lifespan.
Effective segregation of mechanical and electrical components prevents mutual interference from temperature and electromagnetic fields, resulting in a leak detector that operates with heightened stability and reliability.
Remote Control Capabilities: Through a dedicated mobile app, users have the ability to remotely initiate, halt, and zero the leak detector. Additionally, real-time leak rate monitoring is conveniently accessible.
