Powerful Functions

• Professional test mode provides flexible and rich control functions to meet the needs of scientific research.
• Provide oxygen permeability curve, oxygen transmission coefficient curve, temperature curve and humidity curve.
• Ultra wide test range, meet the barrier test (customized) of various materials.
• Ultra wide temperature range, meet the barrier test at different temperatures (customized).
• The gas purification device independently developed by Labthink can remove trace oxygen in nitrogen and provide oxygen free carrier gas (optional).

Testing Principle

The sample is clamped between the test chambers, oxygen or air flows on one side of the film, and high-purity nitrogen flows on the other side of the film. Oxygen molecules diffuse through the film into the high-purity nitrogen in the other side. The flowing nitrogen is carried to the sensor. Through the analysis of the oxygen concentration measured by the sensor, the oxygen transmittance is calculated.

High-Precision Oxygen Permeability Measurement

Equipped with an advanced coulometric sensor, the instrument guarantees accurate and consistent oxygen barrier detection across a broad measurement range (0.01-50,000 cc/m224h). It rapidly delivers results within five minutes, making it suitable for time-sensitive laboratory environments and reliable packaging material analysis. The robust stainless steel chamber resists corrosion and maintains integrity over years of intensive lab use.


Convenient Workflow and Automated Features

Manual sample placement enables quick loading of packaging specimens of various sizes (50 mm 50 mm to 150 mm 150 mm). Testing is fully automated, and the system supports up to three specimens analyzed in parallel, boosting laboratory throughput. Calibration is performed automatically using standard gases, ensuring continuous accuracy and minimal intervention.


Comprehensive Data Management and Safety

With the ability to store 1000 historical test records, labs can archive and retrieve results efficiently. LCD touch screen offers intuitive navigation in multiple languages. Over-temperature, over-pressure, and sensor fault alarms protect operators and equipment, while automatic temperature and humidity controls maintain precise test conditions.
