Gas permeability tester N600T

for oxygen transmission rateair permeabilityhardware

Introduction
N600T Air Permeation Resistance Tester is designed according to GB/T 44587-2024. Based on the differential pressure test principle, it is intended for measuring air permeation resistance of oxygen absorber packaging films used in food packaging and related materials.

Test Principle
With a test area of 6.42 cm2 and a controlled differential pressure (default 0.05 MPa), the instrument measures the time required for 100 mL of air to pass through the packaging film sample under test conditions.

Standards
GB/T 44587-2024 General Rule for Quality of Oxygen Absorber Packaging Films for Food
