Details
GPT200 can measure the permeability of rubber to gases under steady-state conditions. The tester can be used for evaluating the air permeability of inner tyres, tubeless tyres, hoses, balloons and other rubber containers, seals and films.
GPT200 works with gas chromatography system. The cavity of a test cell, maintained at a constant temperature, is divided by a disc test piece into a high-pressure and a low-pressure side. The high-pressure side is connected to sample gas(N2) while the low-pressure connected to carrier gas (H2), the N2 permeates into the H2,which is a very low volume and can be measured by gas chromatography system. Following ISO2782.
