Gas permeability tester GTR-G3

leakagetransmission ratefor film

Gas Permeability Tester is based on the differential pressure method, and is professionally applicable to the determination of gas transmission rate (GTR) as well as solubility coefficient, diffusion coefficient and permeability coefficient of plastic films, composite films, high barrier materials, sheeting, aluminum foils, rubber, tire and permeable membrane Advanced Technology -The three permeation cells are completely independent, and can test three identical specimens or distinct specimens simultaneously -Equipped with imported high-precision vacuum sensor and pressure sensor ensure the test accuracy -World's first advanced water circulated temperature control system, realized temperature auto control and wider temperature range -Independent temperature control for upper/lower chamber and electrolytic sensor, which ensures the accuracy of the test results -Self-developed airtight piping system reduces system errors and makes test results more accurate -Unique sample anti-leakage structure design, ensure the seal stability of samples -Automatic pressure holding function, which can adjust the pressure of the upper chamber in real time to ensure the constant pressure difference between the upper/lower chambers during the test -With professional operating system, the test process is completed the results are displayed automatically -With high-speed vacuuming capability, more thorough degassing, short test cycle and high efficiency High-end Configuration -Two test modes: proportional mode and standard mode -The system has self-checking capability to ensure that the equipment is in normal test state at any time
