Container Gas Permeability Tester

Product Description

Digital Air Permeability Tester

This tool is grounded on the differential pressure technique, and job wise applicable to the examination of gas transmission rate of ended package vessels. Test gases could be oxygen, air, carbon dioxide, nitrogen, and testable containers comprise several bottles of juice, tea, carbonated drinks, as well as packages of dairy products, edible oil, metal containers and washing supplies.

Principle

The pre-conditioned empty container is fixed in the gas diffusion cell to make a sealed fence. The inner and outer compartments of vessel are expatriate firstly, trailed by the removal of the whole cell. A stream of test gas is afterward presented into the expatriate outer compartment and a continuous pressure change is produced between two compartments. The gas pervades through the sample from higher pressure side into the less pressure side. The gas penetrability and other fence features of the example can be got by analyzing the pressure alteration of inner chamber.

Applications :

This test instrument is used to the determination of gas porousness of:

Examine the gas permeability of manufactured package containers, e.g. juice bottles, edible oil packages, carbonated drinks bottles, dairy product packages, tea drinks bottles, metal packages and washing supplies packages
