i-Gastra 7200 Gas Permeability Tester is based on differential pressure/manometric method. It is available for gas transmission rate test of various films, sheeting, paper, paper board and many others.

Functionality

  • Diffusion coefficient, solubility coefficient and permeability coefficient measurement
  • Testing three specimens at the same time in three test cells and providing average value of the three tested specimens
  • Broad humidity control range and automatic temperature control to support various non-standard test conditions
  • Proportional and standard test modes are available in this instrument
  • Test range is wide enough to meet the test requirements of extremely high- or low-barrier materials
  • Data curve fitting function for any temperature makes it possible to obtain test results at extreme conditions
  • Support tests for single gas, mixed gas and inflammable as well as explosive gases (customization required)
  • Reference film for fast and accurate calibration
  • Top quality parts and components made by world famous brands are used to ensure reliable overall product performance

Design

  • Patented integrated design of three test cells improves the test efficiency and reduces the space occupancy of the instrument.
  • Embedded computer control system provides safer and more reliable data management as well as test operation.
  • The gas transmission rate tester can be easily operated with a mouse, a keyboard, and a monitor, without requiring a PC.
  • The GTR tester is equipped with four USB ports and dual Internet ports for convenient data transmission.
  • Sophisticated energy consumption and test environment monitoring and analysis functions for better test accuracy and reliability. (Relevant sensors are needed. For more information, please refer to the configuration in Technical Specifications.)

Software

  • Interface: Windows-based operating interface
  • Statistics: easy calculation for historical results, instrument usage, energy consumption, and large statistical information
  • Data Comparison: by presetting target value and range, the system automatically generates data comparison after each test and intelligently judges whether the specimen passes or fails the test
  • Test Report: can provide detailed test reports in various customized patterns
  • Energy Consumption and Test Status Monitoring (Additional Sensors Required): the system monitors and displays real-time voltage, current, energy consumption of instrument as well as ambient temperature and relative humidity during the test, which serves to evaluate test data reliability
  • User Management: multi-level account management for better data management and protection
  • Operation Log: system automatically records all the operations by the user, which is easy to review
