• Labthinks unique high-precision automatic pressure compensation technology in the test process realizes a constant pressure difference in the high-pressure chamber, and the pressure fluctuation is less than 0.2 kPa.
• The pressure in high-pressure chamber can be set within the range of 10kPa210kPa, the pressure can be maintained accurately and stably by the system.

High Efficiency

• Six independent test cells with standard area, three times the number of test cells in traditional oxygen permeability testing instruments.
• Six specimens can be tested simultaneously under the same testing condition, delivering independent test result.
• Medium and low barrier materials, test time <4 hours (including vacuumize time).
• High barrier materials, test time <4 hours (including vacuumize time).
• Automatic specimen clamping saves time and effort. The clamping force is consistent, resulting in better air tightness.

Intelligent control

• 12 touch-screen tablet powered by WindowsTM 10 operating system makes the operation simpler and more convenient.
• Automatic test mode requires only inputting temperature and humidity, one click start, the test is fully automated.
• Intelligent test chamber hood automatically opens and closes with sound and light alert

Safe and reliable

• System security -- Built-in Labthink's unique high-end industrial computer prevents system failures caused by computer viruses, ensures operational reliability and data storage security.
• Operation safety-- Equipped with intelligent optics sensors which give sound and light alert to ensure safe operation.
• Performance reliabilitythe instrument adopts components of global renowned brands, to ensure stable and reliable performance.

Space saving

• The width of the instrument is only 1/3 of the traditional six-cell instrument, saving space for a laboratory.

Powerful functions

• Professional test mode provides flexible and diverse control options to meet various needs of scientific research.
• The system provides gas transmission rate curve, gas transmission coefficient curve, and temperature curve.
• Ultra-wide test temperature range to enable the barrier tests under various extreme temperature (Optional).
• Ultra-wide test range to meet the barrier test of various materials (customize).
• Tests of hazardous gases such as H2aCH4 are applicable (Customize).

Test Principle

The pre-conditioned specimen is mounted in the test cell as to form a sealed barrier between two chambers. The lower-pressure chamber (lower 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 (upper chamber) and a constant pressure (adjustable) difference is generated between the two chambers. The gas permeates through the specimen from higher pressure side into the lower pressure side. The gas permeability and other barrier properties of the specimen can be obtained by analyzing the pressure changes in the lower chamber.
