Product Overview

NHJ600 Helium Mass Spectrometer Leak Detector

Overview

Built-in backing pump for easy transportation, such as for leak detection services and laboratories.

Utilizing helium mass spectrometry and counter-diffusion principles, adopting 180° non-uniform magnetic field and automatic control technology, it realizes automatic helium peak scanning, automatic calibration, and automatic range switching.

It features portability, fast startup, fast operation, high sensitivity, accuracy, and speed.

The unique gas path design increases the helium pumping speed, shortens the helium background cleanup time, and effectively prevents helium contamination.

The leak detection port is equipped with a custom precision filter device, which can effectively prevent debris particles or copper powder from entering the instrument.

It has multi-mode functional inputs and outputs, easily connecting to various automation equipment.

The mechanical circuit and electrical circuit are effectively separated to avoid mutual interference from temperature, electromagnetic fields, etc., making the leak detector operation more stable and reliable.

The minimum detectable leak rate is low, sensitivity is high, and the detection range can reach 11 decades.

Other Features

  • Handheld remote control unit with a remote control distance up to 150 meters.
  • The leak detector's customized software can be compiled according to customer requirements.
