Product Overview

NHJ480 Helium Mass Spectrometer Leak Detector

Overview

Utilizing helium mass spectrometry and reverse diffusion principle, with a 180° non-uniform magnetic field and automatic control technology, it realizes automatic helium peak scanning, automatic calibration, and automatic range switching.

It features short start-up time, fast operation speed, high detection sensitivity, and strong anti-interference capability.

Performance Features

  • Unique gas path design prevents dust from entering the instrument interior.
  • Multi-mode functional input/output, easy to connect to various automation equipment
  • Dual iridium ion source, strong oxidation resistance, long service life
  • The machine is effectively isolated from the circuit, avoiding interference from temperature, electromagnetic fields and other factors, making the leak detector operation more stable and reliable.

Other Features

  • Multiple measurement units can be selected, detection data is updated in real time, and can be directly output to generate Excel spreadsheets
  • Handheld remote control device, capable of remote detection up to 150 meters distance without obstacles.
