Residual Oxygen Analyzer

Product Introduction

The Headspace Gas Analyzer (residual oxygen analyzer) adopts a portable handheld design and is used to determine the oxygen (O₂) content in the headspace of sealed packaging bags, bottles, cans and other packaging containers, with an optional carbon dioxide (CO₂) detection function.

Application Scope

1. Basic applications
Packaging bags: suitable for testing the O2 and CO2 (optional) content in the gas of various non-negative-pressure packaging bags such as coffee, cheese, milk tea, milk powder, bread, soybean powder, modified atmosphere packaging, ready-to-eat food and medicines.
Packaging containers: suitable for testing the O2 and CO2 (optional) content in the gas of packaging containers such as canned coffee, canned milk powder, canned food, cheese, canned products, Tetra Pak packaging and beverages.
2. Extended applications
Ampoules: suitable for testing the O2 and CO2 (optional) content in the headspace gas of ampoules.

Executive Standards

• JJG 365-2008 Verification Regulation for Electrochemical Oxygen Meters
• JJG 635-2011 Verification Regulation for Carbon Monoxide and Carbon Dioxide Infrared Gas Analyzers

Product Features

• Handheld lightweight design: adopts a handheld lightweight design with a total weight of about 0.5 kg, convenient for laboratory and on-site sampling inspection.
• One-key startup: one-key automatic calibration/test function, reducing operation complexity.
• Low power consumption and intelligent shutdown: equipped with an automatic shutdown function, which can automatically shut down when unattended, effectively extending standby time and reducing energy consumption.
• Fast testing: a single test takes a short time, allowing rapid batch sample detection.
• Visualized startup process: equipped with a 30-second startup countdown display interface, the device status is visible in real time, improving operation certainty.
• Two-point / multi-point calibration: supports two-point calibration and multi-point calibration to correct measurement deviations in different concentration ranges.
• Quick-plug sampling needle protection design: equipped with a quick-plug sampling needle protective sleeve, easy to install and remove, reducing the risk of accidental puncture.
• Headspace gas quantitative analysis: built-in gas detection unit, capable of quantitative analysis of the headspace gas of flexible packaging and rigid packaging.
• Real-time gas path pressure monitoring: built-in gas path pressure detection unit, used to monitor the gas path pressure during the sampling process.
• High-performance imported sensor: uses a high-performance imported sensor. O₂ detection uses the electrochemical sensing principle, and CO₂ detection (optional) uses the NDIR principle (non-dispersive infrared absorption).
• Chinese and English interface switching: supports Chinese/English interface switching; the language confirmation key operation logic is clear, making the switching confirmation clearer and preventing mis-touch.
• Software upgrade: supports continuous software upgrades and continuous function optimization, providing continuous protection for instrument performance and user experience.
• Automatic saving of test data: has automatic data storage and power-off automatic memory functions to prevent data loss.
• Large-capacity data storage: built-in data storage of up to 2000 records, meeting the needs of large data volume storage.
• USB data transmission: equipped with a USB interface for quick data transmission.
• Bluetooth printing: a Bluetooth printer is optional to output test results.
