Model N**0 Gas permeation tests the gas transmission rate (GTR) of packaging material.
This instrument is widely used in food industry, pharmaceutical industry, cosmetics flexible packaging materials industry (plastic film, barrier materials, sheets, metal aluminum, PVC, PVC sheets), college, university and quality institution for gas(O2,CO2,N2,ect)permeation test and quality control.
It carries the standards of ISO ********1,ISO******1,GB/T ********0,ASTM D****-*2(***3),YBB*******3.
Working principle
Use different pressure method .Put the prepared sample between the upper and lower chamber ,clamping it. Then do the vacuum for the whole system .Close the lower testing chamber, input test gas in the upper chamber, make sure form constant pressure between the two side of test sample, for differential conditions, the gas will permeate from the high pressure to lower pressure side, by monitoring the pressure of the lower pressure side to get parameters of various kinds testing samples.
