VAC-V1 Gas Permeability Testing Instrument  ASTM D1434
 is based on the differential pressure method, and is professionally applicable to the determination of gas transmission rate as well as solubility coefficient, diffusion coefficient and permeability coefficient of plastic films, composite films, high barrier materials, sheeting, metal foils, rubber, tires, and permeable membranes.

1.Gas transmission rate, solubility coefficient, diffusion coefficient, and permeability coefficient of the specimen could be obtained at one operation

2.The instrument comes with two test modes: proportional mode and standard mode

3.Test range could be extended based on user requirements to test materials with high permeability

4.High precision temperature control to meet different test conditions

 

Applications :

1.Films
2.Sheeting
