NHJ400 Helium Mass Spectrometer Leak Detector (New Energy Application)
Split-type, dedicated to the new energy industry
The NHJ400 series features a split-type design with a separate mass spectrometer chamber and backing pump, making it a fully automatic mobile helium mass spectrometer leak detector. With its simple structure and superior performance, it is suitable for a wide range of industries. The unique gas circuit design and core self-developed mass spectrometer chamber ensure stable signals and strong resistance to magnetic interference.
Mechanical and electrical isolation, dual-iridium filament ion source offering oxidation resistance and long service life. 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 triggers an automatic alarm when the preset pressure is not reached. A handheld remote control unit (up to 150 m) with WiFi connectivity supports APP remote control. Auto-zero and automatic range switching enable real-time data updates and direct Excel report generation.
The software is customizable and features a rotatable color touchscreen.
Split-type layout with oil pump, classic model featuring fully automatic mobile operation. Simple and reliable structure, suitable for various leak detection applications in the new energy industry.
