Helium leak detector
MDHJ-L004 series leak detector is a fully automatic mobile helium mass spectrum leak detector, mute wheel design, suitable for many harsh vacuum industry.
Using helium mass spectrometry and inverse diffusion principle, using 180° inhomogeneous magnetic field and automatic control technology. Automatic helum peak scanning, automatic calibration and automatic range switching are realized.
lt has the characteristics of short start time, fast operation speed, high detection sensitvity and strong anti-interference
ability.
Features
Unique gas path design, can avoid dust into the instrument interior
Multi-mode function input, output, easy to connect a variety of automation equipment
Double iridium ion source,strong antioxidant capacity and long service life
The machine is effectively separated from the circut, avoiding the interference of temperature, electromagnetic field and so on.which makes the leak detector run more stable and reliable
APP;use mobile phone APP remote over-control leak detector to start, stop, zero. Real-time monitoring leak detectorshows leakage rate.
