NHJ-800 helium mass spectrometer leak detector 

Introduction:

NHJ-800 dry pump mobile helium mass spectrometer leak detector is an oil-free, pollution-free leak detector

The NHJ-800 dry pump mobile helium mass spectrometer leak detector can pass the preset pressure. When the pumping is empty, the preset value is not reached, and the leak detector automatically alarms.

The NHJ-800 dry pump mobile helium mass spectrometer leak detector has a variety of measurement unit selection, the test data is updated in real time, and the output is directly generated into an Excel spreadsheet.

The NHJ-800 dry pump mobile helium mass spectrometer leak detector has a variety of large leakage protection modes to fully protect the ion source from being oxidized and leaking into the atmosphere.

The NHJ-800 dry pump mobile helium mass spectrometer leak detector has a handheld remote control unit that can be remotely detected without obstruction up to 150 meters.

The NHJ-800 dry pump mobile helium mass spectrometer leak detector can be started with one button, automatically zeroed, and automatically calibrated.

Features:

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.
