Test Principle
The pre-conditioned specimen is clamped in the test cell, oxygen or air flows on one side of the specimen while a stream of high purity nitrogen flows on the other side. Oxygen molecules permeate through the specimen into the nitrogen side and are carried to the coulometric sensor. The sensor analyzes the oxygen concentration and calculates the oxygen transmission rate and other factors.

FAQ's of Oxygen Transmission Rate Test in Plastic Pudding Cups:
Q: How does the coulometric sensor method function in this OTR tester for pudding cups?
A: The tester employs the coulometric sensor method with equal pressure, where oxygen permeating through the pudding cup sample is quantitatively detected under controlled test atmospheres. This high-sensitivity method provides rapid, accurate readings essential for assessing packaging barrier properties.
Q: What packaging types and specimen sizes can be analyzed with this device?
A: Designed primarily for plastic pudding cups, the tester accommodates samples with diameters from 30 to 120 mm and heights up to 350 mm. It supports testing one to three specimens simultaneously, making it ideal for batch quality assessments in food packaging.
Q: When should I calibrate the instrument and how is calibration managed?
A: Calibration frequency is user-selectable and software-assisted for convenience and precision. Regular calibration is recommended as part of routine quality control or when changing key test parameters to maintain measurement accuracy within 2% of the reading.
Q: Where can I retrieve and export the test data generated by the machine?
A: Test data can be viewed on the digital LCD display in real time and saved onboard (up to 400 results). Users can export data in CSV or PDF formats via the RS232 or USB interface, facilitating further analysis and regulatory compliance.
Q: What safety measures are included during operation?
A: The tester incorporates over-pressure protection and leak alarms, ensuring safe operation under laboratory conditions. The system automatically alerts users to issues, safeguarding both samples and staff.
Q: What is the general procedure for conducting an OTR test on a pudding cup?
A: After conditioning the sample (15-60 minutes), the cup is placed within the 2.5L testing chamber. Test parameters such as temperature (15-50C), humidity (30-90% RH), and test speed (0.1-1.0 L/min) are configured automatically. The system then performs the measurement and saves the results for export.
Q: What are the main benefits of using this OTR tester for packaging evaluation?
A: This equipment delivers precise, automated OTR analysis, improves quality assurance, and supports regulatory compliance. Its versatility, high memory capacity, rapid response, and robust safety features streamline laboratory workflow and product development for food packaging manufacturers.
