C650M Headspace Gas Analyzer is featured with handheld design and equipped with high precision sensors and air pump supplied by globally well-known manufacturers. It can provide accurate and fast evaluation of the volume of oxygen and carbon dioxide (with optional CO2 sensor) in sealed packages, bottles and cans, etc. Because of its portable design, the instrument can be used to measure the volume and proportion of oxygen and carbon dioxide on production lines, in warehouses or in laboratories, to serve as a guide for production.
Handheld and portable design, easy-to-operate with one hand, suitable for tests on production line
Auto shutdown for energy saving
One-button calibration, simple and efficient
Components and parts are supplied by global well-known manufacturers, which guarantee stable performance of the instrument
Protective cover for sampling probe to ensure the safety of the operator
Embedded gas sensors for accurate analysis of the gas contents inside flexible or rigid packages
Embedded pressure sensor for accurate determination of the vacuum degree inside the package
CO2 sensor uses NDIR technology, patented solid state LED, detector and gold-plated optic components
The sensors are supplied by globally well-known manufacturers, which have ultra-high precision, low fault rate and long service life
Chinese and English language operating system can meet different requirements of the users
Automatic data storage, power failure memory to prevent data loss
Up to 1200 test results can be stored
Equipped with wireless micro-printer for convenient data printing (optional)
Equipped with standard USB ports and professional software for convenient PC connection and data transfer (optional)
The gas inside the test package is brought to the gas sensor by the air pump. The instrument analyzes the volume of oxygen and carbon dioxide (optional) contained in the sample gas by calculating the electrical signals generated by the gas sensor. When the preset condition is met, the test is completed and the system records the oxygen and carbon dioxide (optional) concentration.
Packaging Bags Test the volume of O2 and CO2 (optional) in headspace of non-vacuum sealed packaging bags of coffee, cheese, milk tea, milk powder, bread, bean powder, instant food and drugs, etc.
Packaging Containers Test the volume of O2 and CO2 (optional) in headspace of packaging containers of coffee, milk powder, food, cheese, can, Tetra Pak and beverage, etc.
Ampoule Bottles Test the volume of O2 and CO2 (optional) in headspace of ampoule bottles
