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.

A: Calibration should be done regularly or after major maintenance. The device offers both automatic and manual calibration using standard gas, guaranteeing ongoing measurement reliability and accuracy.
Q: Where should the OTR tester be installed for optimal performance?
A: It is recommended to place the equipment in a dust-free, low-vibration area with controlled ambient conditions (humidity: 10-90% RH, temperature: 15C-45C) to ensure consistent and accurate test results.
Q: What is the process for preparing samples for OTR testing?
A: Samples can be up to 150 mm wide and typically sized at 100 mm or customized. The tester features a programmable pre-conditioning cycle to standardize sample conditions before testing. Up to three samples can be tested simultaneously for comparison.
Q: How is data managed and retrieved from the OTR tester?
A: Test results are stored internally (up to 1000 tests) and can be exported using USB or RS232 interfaces. Digital and printable reports simplify documentation and ensure seamless integration into quality management systems.
Q: What are the benefits of using this OTR tester for ready-to-eat meat packaging applications?
A: Accurate OTR results help manufacturers and exporters select optimal packaging materials, leading to improved food safety, longer shelf life, and compliance with international regulations. The multi-sample capability enhances testing efficiency in food packaging R&D and production quality control.
