Helium mass spectrometer leak detector

Helium mass spectrometer leak detector

1、 Product usage and overall requirements:

The HYHJ-400 series leak detector is a fully automatic mobile typeHelium mass spectrometer leak detectorStatic Y-wheel design, suitable for

In many industries with harsh conditions, helium mass spectrometry and reverse diffusion principles are applied, and 180 ° non-uniform magnetic field and fully automatic control technology are used to achieve automatic helium peak scanning, automatic calibration, and automatic range switching. It has the characteristics of short start-up time, fast calculation speed, high detection sensitivity, and strong anti-interference ability.

2、 Performance characteristics

Unique air path design can prevent dust from entering the interior of the instrument, with multi-mode functional input and output, making it easy to connect

Various automation equipment, dual iridium ion source, strong antioxidant capacity and long service life, effectively separate mechanical and electrical components, avoid interference from temperature, electromagnetic fields, etc., making the leak detector operate more stably and reliably.
