• Automatic sample clamping, saving time and effort, ensuring consistent clamping force and better sealing.

Intelligent Operation

• The 12 Inch Touch panel of windows system is used for more convenient operation.
• Automatic mode - after inputting test temperature and humidity and clicking one key, the test proceeds automatically.
• New drawer type test cell, one key automatic in-and-out with sound and light reminder.

Safe and Reliable

• Safe Running: Labthinks high-end industrial computer is embedded to eliminate the system failure caused by computer virus and ensure the operation reliability and data storage security.
• Safe Operation: equipped with optical and other intelligent sensors as well as intelligent sound and light alarms to ensure the operation safety.
• Safe Performance: the instrument uses global renowned brand components with stable and reliable performance.

Powerful Functions

• Professional test mode provides flexible and plentiful control functions to meet the needs of scientific research.
• Display oxygen/water vapor transmission rate curve, oxygen/water vapor transmission coefficient curve, temperature curve and humidity curve.
• Wide temperature range, allowing the barrier test at different temperatures (customized).
• The gas purification device independently developed by Labthink can remove trace oxygen in nitrogen, providing oxygen-free carrier gas (optional).

Testing Principle

The pre-treated sample is clamped between the test chambers, oxygen or nitrogen with stable relative humidity flows on one side of the film, and the high purity nitrogen flows on the other side; oxygen or water molecules diffuse through the film into high-purity nitrogen on the other side, and are carried to the sensor by the flowing nitrogen. By analyzing the oxygen or water vapor concentration measured by the sensor, the oxygen or water vapor transmission rate can be calculated.
