About This Product
The gas permeability of a rubber sheet is the rate at which gas flows through it under steady conditions when there is a pressure difference between its two faces at a controlled temperature. The property matters when evaluating compounds for inner tubes, tubeless tyre liners, hoses, balloons, other gas containers, seals and diaphragms. This tester keeps the metal blocks of its test cell at a set temperature and reads the volume of gas that has passed through on a glass capillary.
Frequently Asked Questions
Q1. What does the Gas Permeability Tester measure?
It measures the permeability of rubber sheets to gases, defined as the rate of volume flow of gas under steady state conditions between opposite faces of a unit cube of solid rubber under unit pressure difference at a controlled temperature.
Q2. How is the temperature controlled?
The metal blocks of the test cell are heated independently by cartridge-type heaters, and each block has its own digital temperature indicator cum controller. Both blocks are insulated to avoid heat losses.
