GTR-G3

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

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.
