Product Description

Product Description

NHJ-400N Helium Mass Spectrometer Leak Detector Vacuum Helium Leak Detection Analyzer  testing machine

Overview

NHJ-400 series leak detector is a fully automatic mobile helium mass spectrum leak detector, mute wheel design, suitable for many harsh vacuum industry.

Using helium mass spectrometry and inverse diffusion principle,using 180° inhomogeneous magnetic field and automatic control technology. Automatic helium peak scanning, automatic calibration and automatic range switching are realized.

It has the characteristics of short start time, fast operation speed, high detection sensitivity and strong anti-interference ability.

Performance characteristics

Unique gas path design, can avoid dust into the instrument interior

Multi-mode function input, output, easy to connect a variety of automation equipment

Double iridium ion source, strong antioxidant capacity and long service life

The machine is effectively separated from the circuit, avoiding the interference of temperature, electromagnetic field and so on, which makes the leak detector run more stable and reliable.

Easy to Operate
 

Leak Detection Feature: The leak detector can be preset to a specific pressure, and if the pressure does not reach the set value during the evacuation process, the detector will automatically trigger an alarm.

Multiple measurement unit options, real-time data update, and direct output to generate an Excel spreadsheet.

Various leak protection modes to fully protect the ion source from oxidation and prevent the molecular pump from being impacted when exposed to the atmosphere.

Handheld remote control unit with unobstructed control distance up to 150 meters.

One-touch start, automatic zeroing, and automatic calibration.
