    AI Overview
    An OTR (Oxygen Transmission Rate) tester measures the rate at which oxygen permeates through plastic films, barrier materials, or finished packages, typically following standards like ASTM D3985. These analyzers use sensors—often coulometric—to determine barrier efficiency, which is critical for extending the shelf life of food, pharmaceutical, and medical products. 
    Key Features and Types 
    • Methodology: Most testers use the coulometric sensor method or differential pressure method to detect oxygen flow.
    • Applications: Used for testing flexible films, bottles, and complete packaging, notes Labthink international.
    • Environmental Control: Advanced models allow testing under specific temperatures and relative humidity (RH) to simulate real-world storage conditions, says
      AMETEK MOCON.
    • Measurement Units: Results are generally expressed in

    How to measure oxygen transmission rate?
    At a selected temperature and humidity, a barrier film is sealed between a chamber containing oxygen and a chamber void of oxygen. A coulometric sensor measures the oxygen that is transmitted through the material.

    What is a good oxygen transmission rate?
    A "good" Oxygen Transmission Rate (OTR) depends on the product's tolerance to oxygen, but in packaging applications, materials with an OTR below 1 cc/100 in²/24 hr (≈15.5 cc/m²/24 hr at 23 °C, 0% RH) are considered high oxygen barriers, ideal for preserving oxygen-sensitive goods.Jul 3, 2025
