The residual oxygen meter, also known as the headspace gas analyzer, was developed and produced with reference to the "JJG365-2008 Electrochemical Oxygen Determination Instrument". It is used to measure the oxygen content, carbon dioxide content, and mixing ratio in hollow packaging containers such as sealed packages, bottles, and cans. It can quickly and accurately assess the content and ratio of gas components in production lines, warehouses, laboratories, etc., thereby guiding production and ensuring the shelf life of products.

• Handheld design, one-handed operation, lightweight and easy to carry, suitable for on-site testing in production;
• Quick-insert sampling needle protective cover to ensure test safety;
• Built-in gas sensor for accurate analysis of the gas content inside soft and hard packaging;
• Built-in pressure sensor for accurate measurement of the internal vacuum degree of the sample;
• The sensor is imported from a world-renowned brand, with ultra-high test accuracy, ultra-low failure rate and ultra-long service life;
• One-button operation and calibration, intuitive operation interface, and remote upgrade and maintenance;
• Supports one-touch switching between Chinese and English to meet different language requirements;
• Has automatic shutdown, automatic storage, and automatic memory when power off to prevent data loss;
• Built-in data storage can reach 2000 groups, and is equipped with a USB interface for data import and export;
• Built-in 6800mAh large-capacity lithium battery provides portable and long-lasting power support;
