GPT200 Gas Permeability Tester
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,GBT 7755.
With Omron touch screen,
more stable and easy operation.
With PLC controller and
E5EC temp gauge, can keep long stable running.
With H2 and N2 generator
can keep stable testing for the whole process.
Gas chromatography can get
the higher accuracy permeability coefficient.
