Description

Product overview

  • The C650M Headspace Gas Analyzer is a handheld portable instrument for fast, accurate measurement of oxygen (O2) and optional carbon dioxide (CO2) volume and concentration in sealed packages, bottles and cans for production-line, warehouse or laboratory use.
  • Designed for on-site headspace analysis to support production and quality control.


Key features

  • Handheld, one-hand operation suitable for production-line testing
  • Auto shutdown to save energy
  • One-button calibration for quick setup
  • Protective cover for sampling probe to ensure operator safety
  • Embedded gas sensors for accurate analysis in flexible and rigid packages
  • Embedded pressure sensor for accurate vacuum determination inside packages
  • Optional CO2 sensor (NDIR) with patented solid-state LED, detector and gold-plated optical components
  • Industrial-grade touchscreen with one-button operation, intuitive UI, remote upgrade and maintenance capability
  • Chinese and English operating system
  • Automatic data storage with power-failure memory; up to 1200 test results can be stored
  • Optional wireless micro-printer for on-site data printing
  • Optional standard USB ports and professional PC software for data transfer and PC connection


Test principle

  • Sample gas is drawn by an air pump to the gas sensor. The instrument analyzes O2 (standard) by electrochemistry and CO2 (optional) by NDIR infrared absorption. Electrical signals from sensors are converted to concentrations; the test completes and results are recorded when preset conditions are met.


Applications

  • Basic applications
    • Packaging bags: headspace O2 and optional CO2 in non-vacuum sealed bags (e.g., coffee, cheese, milk tea, milk powder, bread, bean powder, instant food, pharmaceuticals)
  • Packaging containers
    • Headspace O2 and optional CO2 in containers (e.g., coffee, milk powder, canned food, Tetra Pak, beverages)
  • Extended applications
    • Ampoule bottles: headspace O2 and optional CO2 in ampoule bottles


Configurations

  • Standard: instrument, sampling probe, filter, seal gasket
  • Optional: professional software, micro-printer, B2227 test frame for headspace analyzer, B2226 underwater sampling set, CO2 sensor, pressure sensor


Specifications

  • Model: C650M
  • Testable gases: O2 (standard); CO2 (optional)
  • Test principle: O2 by electrochemistry; CO2 by NDIR infrared absorption
  • Sensor service life: O2 sensor ≈ 2 years (in air); CO2 sensor > 15 years
  • Test range: 0 ~ 100%
  • Resolution: 0.01%
  • Test accuracy: O2 ±0.2%; CO2 ±(0.03% + displayed value × 5%)
