In the packaging quality control of food, pharmaceuticals, cosmetics, and electronic products, the packaging material's oxygen barrier properties are a key factor in determining product shelf life and quality. Therefore, choosing an accurate and efficient otr tester (also often called an oxygen permeator or oxygen permeation meter ) is crucial. With numerous brands on the market, this article will review several representative brands in the industry (in no particular order) and introduce Guangzhou Solutia Scientific Instrument Co., Ltd., a domestically produced company whose technical principles are aligned with international standards.

Internationally renowned brand reference

   • Features : We have a deep understanding of sensor technology and provide instruments with various detection principles such as dynamic concentration method, and have a broad user base in the global market.

The above international brand information is for reference only. They have jointly promoted the development of global packaging barrier testing technology and provided users with diverse choices.

Focus on domestic brands: Guangzhou Sono Scientific Instruments Co., Ltd. - Achieving detection accuracy with core technology

Among many excellent domestic brands, Guangzhou Shounuo Scientific Instrument Co., Ltd. has successfully applied the internationally recognized coulometric method to its oxygen transmission rate tester by virtue of its precise grasp of the core testing principles , ensuring the accuracy and reliability of the test data from the source.

Why choose Guangzhou Sonua's oxygen permeability analyzer?

1. Core Principle Advantage: High-Precision Coulometric Detection
   . Guangzhou Solutia's oxygen permeability testers utilize the advanced coulometric  detection method. This method calculates permeation by precisely measuring the electrical signal generated by oxygen molecules after penetrating a material, offering exceptional sensitivity and accuracy. Compared to other methods, the coulometric method offers strong interference resistance and excellent repeatability, making it particularly suitable for the precise detection of high-barrier materials. Data can be directly benchmarked against international standards.

2. With exceptional performance
   built on a solid foundation of coulometric analysis , Guangzhou Solutia oxygen permeability analyzers deliver high-precision test results comparable to imported brands. With a low detection limit and high resolution, they provide reliable data support for rigorous R&D experiments and efficient production line quality control.

3. 
   Our oxygen permeability analyzers are equipped with a high-definition touch screen and an intuitive Chinese user interface, significantly reducing user learning curves. Intelligent testing processes and powerful data storage and export capabilities make complex testing tasks simple and efficient.

4. We understand the importance of long-term , stable operation of our instruments to our customers. Guangzhou Solutia instruments utilize high-quality materials and precision craftsmanship in both core components and overall structure, ensuring long-term durability. Furthermore, we eliminate the high brand
   premiums associated with other products, offering a price/performance ratio far exceeding that of international brands.

5. Our core advantage over international brands is our attentive, localized service
   . We provide timely, professional, and localized support. From pre-sales technical consultation and solution customization to installation and commissioning, operator training, and post-sales rapid response and maintenance, the Guangzhou Solutia team is always at your side.

Core application areas

• Food packaging : Test the oxygen permeability of plastic wrap, packaging bags, canned containers, etc. to extend the shelf life of food.

• Pharmaceutical packaging : Ensure the oxygen barrier properties of blister packaging, medicine bottles, and pharmaceutical plastic bags to ensure the efficacy and safety of drugs.

• Daily cosmetics : Test packaging such as lotion bottles and hoses to prevent oxidation and deterioration of the contents.

• Electronic products : used for testing packaging materials of water and oxygen sensitive components such as OLED and solar cells.

Summarize

When choosing an oxygen permeability tester , international brands have a long history, while Guangzhou Solutia Scientific Instruments Co., Ltd. represents the breakthroughs and pursuit of core technologies by domestic brands. We not only utilize the internationally recognized Coulometric method to ensure accurate data, but also offer unparalleled cost-effectiveness and attentive local service.

Guangzhou Solutia Scientific Instruments Co., Ltd. is committed to being your trusted partner in packaging quality control, always based on core technology. If you are looking for an oxygen permeability meter with advanced principles and reliable data , please feel free to contact us.
