NHJ-600 Helium Mass Spectrometer
Giới thiệu
NHJ-600 series leak detector is a fully automatic mobile helium mass spectrometry leak detector with silent wheel design, which is suitable for many industries with harsh conditions
Helium mass spectrometry and reverse diffusion principle are used, 180° non-uniform magnetic field and automatic control technology are adopted. Automatic helium peak scanning, automatic calibration and automatic range switching are realized
It has the characteristics of short startup time, fast operation speed, high detection sensitivity and strong anti-interference ability
NHJ-600 Helium Mass Spectrometer
Performance Characteristics
Unique air path design, can avoid dust into the instrument
Multi-mode function input and output, easy to connect various automation equipment
Double iridium ion source with high oxidation resistance and long service life
The machine and circuit are separated effectively, avoiding the interference of temperature and electromagnetic field, making the leak detector run more stable and reliable
