In packaging for food, pharmaceuticals, electronics, and medical devices, the oxygen barrier performance of materials directly affects product shelf life, safety, and functionality. The Oxygen Permeability Tester (also known as OTR Tester) is a critical instrument for evaluating this performance, providing key data for material development, quality control, and packaging design.

However, operators often encounter issues with their Oxygen Permeation Analyzers such as abnormal test data, equipment failure to start, or sensor malfunctions. This article addresses common OTR Tester problems and solutions to ensure testing accuracy and reliability.

1. Abnormally High or Fluctuating OTR Values

When Oxygen Permeability Tester results are significantly higher than expected:

1. Improper Specimen Sealing: Scratched or aged seals in the OTR Tester can cause edge leakage

2. Low Gas Purity: Impurities in oxygen supply affect Oxygen Permeation Analyzers accuracy

3. Uncalibrated Sensor: Electrochemical sensors in OTR Testers may lose sensitivity

Solutions for Oxygen Permeability Testers:

• Inspect and replace seals in your OTR Tester

• Use high-purity gases with Oxygen Permeation Analyzers

• Recalibrate OTR Testers regularly (every 3-6 months)

2. Abnormally Low OTR Values

When Oxygen Permeation Analyzers show consistently low readings:

1. Gas Pressure Issues: Incorrect oxygen pressure in OTR Testers

2. Low Temperature: Affects Oxygen Permeability Tester performance

3. Expired Sensor: Oxygen Permeation Analyzers sensors typically last 1-2 years

Solutions for OTR Testers:

• Verify gas pressures in Oxygen Permeability Testers

• Calibrate temperature sensors in Oxygen Permeation Analyzers

• Replace expired OTR Tester sensor modules

3. Test Failure to Start or Abort

Common issues with Oxygen Permeation Analyzers:

1. Insufficient Gas Supply: Affects OTR Tester operation

2. Line Blockage: Oxygen Permeability Tester flow restrictions

3. Vacuum System Failure: In Oxygen Permeation Analyzers

OTR Tester Solutions:

• Check gas cylinder levels for Oxygen Permeability Testers

• Inspect lines and replace OTR Tester filters

• Verify vacuum pump performance in Oxygen Permeation Analyzers

4. Maintenance Recommendations for Oxygen Permeation Analyzers

For optimal OTR Tester performance:

1. Regular Calibration: Essential for all Oxygen Permeability Testers

2. Proper Storage: Follow OTR Tester manufacturer guidelines

3. Stable Environment: Crucial for Oxygen Permeation Analyzers accuracy

4. High-Purity Gases: Required for reliable OTR Tester results

Selecting appropriate Oxygen Permeability Testers with proper operation ensures accurate barrier property assessment. Contact OTR Tester manufacturers for unresolved issues with your Oxygen Permeation Analyzers.
