Gas permeation instrument conforms to ASTM D3985, ASTM D2622, ASTM F1307, ASTM F1927, ASTM D1434, ISO 2556, ISO 15105-1, ISO 15105-2, JIS K7126-A and JIS K7126-B, etc.
Gas permeation instrument has the below merits:
- Both Manometric and Coulometric principle tests can be performed by one unit;
- With one test, customer could get six results by two standards of three different samples;
- World original design of Curve-fitting Methodology. Gas transmission rate, diffusion coefficient, solubility coefficient and permeability coefficient of the materials at any temperatures between -273 degree Celsius and 200 degree Celsius can be easily obtained;
- Could be extended to perform special test for toxic and explosive gases;
- Optional multiple test modes enhance operation convenience;
- High automatic control system which can control temperature automatically. |
