Description

NHJ-600 helium mass spectrometer leak detector

 

Introduction to NHJ-600 helium mass spectrometer leak detector:

The NHJ-600 is a fully automatic portable helium mass spectrometer leak detector with a compact size and powerful functions.

Using the principle of helium mass spectrometry and reverse diffusion, the multi-port molecular pump, 180° non-uniform magnetic field and fully 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.

Features of NHJ-600 Helium Mass Spectrometer Leak Detector:

1. The unique gas path design improves the pumping speed of the sputum, shortens the background time of cleaning, and effectively prevents cockroach pollution.

2. Leak detection port: Customized precision filter device can effectively prevent debris particles or copper powder from entering the instrument.

3. Multi-mode function input and output, easy to connect various automation equipment.

4. The machine and the circuit are effectively separated 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 leak rate is low, the sensitivity is high, and the detection range reaches 11 levels.
