NHJ-600 helium mass spectrometer leak detector introduction:
NHJ-600 is a compact and powerful fully automatic portable helium mass spectrometer leak detector.
Based on the principle of helium mass spectrometry and inverse diffusion, multi port molecular pump, 180 ° non-uniform magnetic field and full automatic control technology are used to realize automatic peak scanning, automatic zero adjustment, automatic calibration and automatic range switching. High detection sensitivity and strong anti-interference ability.
NHJ-600 helium mass spectrometer leak detector features:
1. The unique air circuit design improves the suction speed of sputum, shortens the cleaning background time and effectively prevents 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.
