Helium Mass Spectrometer Leak DetectorOil Pump
The NHJ480 is a general-purpose, fully automatic mobile helium mass spectrometer leak detector with a silent caster design, suitable for a wide range of demanding industries. Its unique gas circuit design enhances helium pumping speed, shortens helium background clearing time, and provides protection against contamination and dust.The 180°180 non-uniform magnetic field U-shaped magnet mass spectrometer chamber ensures stable signals and strong resistance to powerful magnetic interference.
The dual-iridium filament ion source offers oxidation resistance and extended service life. The mechanical and electrical isolation design prevents thermal drift and electromagnetic interference, ensuring stable and reliable operation. The large-leak protection mode prevents ion source oxidation and protects the molecular pump from atmospheric shocks.
Large-leak detection: automatic alarm when preset pressure is not reached. A handheld remote control unit (up to 150 meters) with WiFi connectivity supports APP remote control. Auto-zero and auto-range switching, real-time data updates, and direct Excel report generation. Customizable software, equipped with a 7-inch rotatable color touchscreen.
Nine core performance features to handle the most demanding conditions.
From core mass spectrometer chamber to intelligent controls, the NHJ480 combines simple structure with stable performance to meet the fully automatic mobile leak detection needs of general industrial sites.
Fully Automatic Mobile Leak Detection for General Industrial Sites
The NHJ480 is designed for fully automatic mobile leak detection in general industrial sites, with a focus on simple structure and stable performance. Its silent caster design ensures flexible positioning on site, while the optimized gas circuit and self-developed mass spectrometer chamber guarantee reliable operation even under demanding conditions, making it an ideal choice for a wide range of challenging industries.
