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