Gas Permeability Tester
Model No. HV-EXP4604
Gas Permeability Tester - Permeability of rubber sheets to gases is defined as the rate of volume flow of gas under steady state conditions between opposite faces of a unit cube of solid rubber, when subjected to unit pressure difference under a controlled temperature. The measurement of this characteristic is of important in the evaluation of compounds for products such as inner tubes, tubeless tyre liners, hoses, balloons or other gas containers, seals and diaphragms etc. The& Gas Permeability Tester for rubber consists of a test cell with arrangement for maintaining a constant elevated temperature and a horizontal glass capillary system for measuring the volume of gas permeated. The test cell consists of metal blocks having independent arrangements for heating with the help of cartridge type heaters. The temperature of each ck is indicated and controlled individually with the help of individual digital temperature indicators cum coblontrollers. Both the blocks are properly insulated to avoid heat losses..
