NHJ-400  Helium Mass Spectrometer Leak Detector  Brief introduction :

Nhj-400 is a full-automatic mobile helium mass spectrometer leak detector, with the characteristics of large volume and excellent performance, which can be used in many industries. Based on the anti diffusion principle of helium mass spectrometry, the imported molecular pump, 180 ° non-uniform magnetic field and fully automatic control technology are adopted to realize automatic peak scanning, automatic zero adjustment, automatic calibration and automatic range switching, with fast detection speed and detection. High sensitivity and strong anti-interference ability.
NHJ-400  Helium Mass Spectrometer Leak Detector Features:
1. The unique air path design improves the suction speed of sputum, shortens the cleaning background time, and effectively prevents cockroach pollution.
2. Leak detection port: the customized precise filtering device can effectively prevent debris or copper powder from entering the instrument.
3. Multi mode function input and output, convenient to connect various automation equipment.
4. The machine and the circuit are effectively isolated to avoid mutual interference of temperature and electromagnetic field, so that the operation of the leak detector is more stable and reliable.
5. The minimum detectable leakage rate is low, the sensitivity is high, and the detection range reaches grade 11.
