Application Content

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.

Features Content

  • Vacuum differential pressure method
  • Built in embedded system with 24bit Δ-Σ AD, remote maintenance and upgrade
  • One-Click start a test and test automatically stop, no any manual operation is required during
  • the process until the end of the test
  • Do NOT need to preset any test parameters before a test, zero operation experience
  • requirements, proprietary technology
  • 3 specimens test simultaneously and independently
  • According to the test state, the vacuum pump starts and stops automatically, do NOT need
  • manual operation
  • Computer control, multiple test modes: Increment, proportional and intelligent
  • 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
  • Test under various RH conditions with Humidity generator (optional)
  • Built in environment temperature and humidity sensor
  • Permeability coefficient ,solubility coefficient and diffusion coefficient test
  • Various curves display: chambers temperature, test pressure, transmission rates, etc
  • Traceable reference film calibration
  • Supports DSM system (DSM, lab data management system)
