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.

FAQ's of Testing for Food Packaging Oxygen and Moisture Barrier Performance Preserving Nutrients and Flavor:
Q: How does this tester measure oxygen and moisture barrier performance in food packaging?
A: The tester assesses barrier performance using isobaric gas transmission principles combined with electrochemical and capacitive sensors. Samples are prepared, conditioned, and placed in the stainless steel test chamber, where oxygen or moisture permeability is measured digitally. The results indicate how well the packaging preserves nutrients and flavor by limiting oxygen and moisture transfer.
Q: What is the process for preparing samples for testing?
A: To ensure accurate results, samples must be cut uniformly (108 mm x 108 mm) and conditioned to the required humidity and temperature. Three specimens can be tested simultaneously. After preparation, samples are secured in the chamber, and test parameters are set via the microcomputer control.
Q: When should calibration be performed and how is it managed?
A: Calibration should be carried out according to your internal QA protocols or if you notice data deviations. The tester supports both automatic and manual calibration modes, ensuring ongoing measurement precision. Regular calibration is vital for regulatory compliance and maintaining result accuracy.
Q: Where can the stored test data be accessed or exported?
A: All test data-up to 1000 results-can be reviewed directly via the digital LCD interface or exported using the USB port or RS232 interface to a Windows-based analysis software. Results can also be printed directly, making it easy to generate documentation for quality audits.
Q: What are the main benefits of using this oxygen and moisture barrier performance tester?
A: Benefits include high testing accuracy (2%), fast response time (30 seconds), the ability to test multiple specimens at once, robust safety protections, and a user-friendly design. These features help manufacturers ensure packaging quality, comply with food safety regulations, and maintain product freshness and shelf life efficiently.
Q: Is this equipment suitable for various packaging materials and testing environments?
A: Yes, the tester accommodates a wide range of packaging materials used in the food industry. Its flexible measuring range (0.01-10,000 cc/m2/day), adjustable speed, and temperature/humidity settings make it adaptable for diverse environments. The IP54 protection grade and sturdy stainless steel chamber guarantee safe, consistent operation.
Q: How does the device enhance efficiency in quality control processes?
A: With automation, high-speed testing (0.1 to 500 mm/min), data storage for 1000 tests, and rapid digital analysis, the tester streamlines quality control workflows. Its user-centric design and seamless integration with existing data systems further boost laboratory and production line productivity.
