This paper expands on the actual operation of VAC-V1 to test the gas permeability of film. Labthink (Languang) introduced its vacuum differential pressure permeability instrument -VAC-V1 Auto Gas Permeability Tester in the second half of 2004. Over a short span of several months, this instrument has achieved remarkable sales record and will export to Southeast Asia soon. Before that, Labthink has already made successful achievement in the data comparison of international permeability testing. All these have promoted Labthink's position in international market of permeability instruments.
