GTR-G3 GTR Gas Hydrogen Helium Permeability Analyzer
(Differential pressure method)
(Differential pressure method)
GTR-G3 GTR Gas Hydrogen Helium Permeability Analyzer 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.
- 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
- 7" color touch screen, 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
- Gas transmission rate, solubility coefficient, diffusion coefficient and permeability coefficient of the specimen could be obtained at one operation
- Test range could be extended based on requirements to test the materials with low permeability
- Imported components make the operation of the instrument more stable and reliable
- Reference film for fast calibration to ensure accurate and universal test data
- With automatic save function after power failure
- Standard RS232 port for convenient data transfer
- The whole testing process is monitored, automatically recorded, and can be reproduced in the whole process
- The software is equipped with data traceability, which can realize functions such as multi-level authority management, audit trail, electronic signature, etc., which meets the requirements of GMP (optional)
Test Principle
The pre-conditioned specimen is mounted in the gas diffusion cell as to form a sealed barrier between two chambers. The lower-pressure chamber is firstly evacuated, followed by the evacuation of the entire cell. A flow of gas is thereafter introduced into the evacuated higher-pressure chamber and a constant pressure difference is generated between two chambers. The gas permeates through the specimen from the higher pressure side into the lower side. The gas permeability and other barrier properties of the specimen can be obtained by monitoring the pressure changes in the lower chamber.Applications
