Spectromètre de masse à l'hélium NHJ-600
Introduction
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
