Gas Permeation Instrument is applicable in gas permeability tests for the plastic film, laminated film, and sheets under various temperatures.
Gas Permeation Instrument items include gas transmission rate, solubility coefficient, diffusion coefficient and permeability coefficient.
Gas Permeation Instrument conforms to ASTM D1434, ISO 2556, ISO 15105-1, GB 1038 etc.
Gas Permeation Instrument FEATURES:
1. Conforms to manometric principle
2. with world-famous high precise vacuum sensor to ensure accurate test data
3. World original design of Curvefitting Methodology. Gas transmission rate, diffusion coefficient, solubility coefficient and permeability coefficient of the materials at any temperatures between -273degree Celsius~200degree Celsius can be easily obtained
4. Optional multiple test modes enhance operation convenience
5. High in repeatability and lower error
6. High automatic control system
