Accurate Data

Brand new dome design test chamber and 360° air circulation constant temperature technology ensures better temperature stability.

Imported high-precision vacuum sensor can accurately test ultra-high barrier materials with 0.01～0.09cm³/ m³·24h·0.1MPa test range.

Imported pneumatic control system has a low failure rate and an ultra-long service life, ensuring good overall system air tightness and high test accuracy.

Imported vacuum pump can reach 0.2Pa extreme pressure with increased vacuum rate.

The vacuum pump is controlled automatically by the system without manual opening and closing, increases efficiency and saves labor.

Labthink’s 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 10kPa~210kPa, the pressure can be maintained accurately and stably by the system.

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.
