Air Permeability Tester GTR-721

GTR 721 is based on the differential pressure method, and is professionally
applicable to the determination of gas transmission rate as well as solubility
coefficient, diffusion coefficient and permeability coefficient of plastic films,
laminated films, high barrier materials, sheeting,metal foils, rubber, tires and
permeable membranes.

(1) Vacuum differential pressure method
(2) Built in embedded system with 24bit - AD, remote maintenance
and upgrade
(3) One-Click start a test and test automatically stop, no any
manual operation is required during the process until the end of the test
(4) Do NOT need to preset any test parameters before a test, zero
operation experience requirements, proprietary technology
(5) 3 specimens test simultaneously and independently
(6) According to the test state, the vacuum pump starts and stops
automatically, do NOT need manual operation
(7Computer control, multiple test modes: Increment, proportional
and intelligent
(8) The temperatures of chambers which hollow inside and with
circulating water are stable, high precision and wide range, 3
chambers with independent temperature sensors to monitor
(9) Test under various RH conditions with Humidity generator (optional)
(10)Built in environment temperature and humidity sensor
(11) Permeability coefficient ,solubility coefficient and diffusion
coefficient test
(12) Various curves display: chambers temperature, test pressure,
transmission rates, etc
(13) Traceable reference film calibration
(14) Supports DSM system (DSM, lab data management system).
