Helium mass spectrometer leak DX300
Helium leak detector >Overview
This instrument is a mass spectrometry leak detection instrument that uses helium gas as a leak indicator gas for leak detection. It can be tested in two modes: positive pressure suction method and negative pressure vacuum method. It is widely used in scientific research, vacuum, refrigeration, automotive, power, pressure vessels, aerospace and other industries, and has the characteristics of fast response speed, high sensitivity, easy use, and less maintenance.
