NHJ480 Leak Detector Helium Mass Spectrometry Leak Detector Vacuum Spectrometer Leak Detector
Uses
NHJ480 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 helium peak scanning, automatic calibration and automatic range switching are realized.
It has the characteristics of short start time, fast operation speed, high detection sensitivity and strong anti-interference ability.
Functions
Large leak detection function: When the preset pressure is not reached during evacuation, the leak detector will automatically alarm and prompt.
Multiple measurement unit options, real-time update of detection data, and direct output to generate Excel tables.
Multiple large-leak protection modes are provided to fully protect the ion source from oxidation and prevent the molecular pump from being impacted when exposed to the atmosphere.
Handheld remote control unit, with unobstructed range up to 150 meters for remote detection.
One-click start-up, automatic zero adjustment, and automatic calibration.
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 circuit, avoiding the interference of temperature, electromagnetic field and so on, which makes the leak detector run more stable and reliable.
