This Gas Analyser was developed as a quality control device with a wide range of features which can be used with minimal training. As a result, this analyser provides a key analytical solution to cover your food packaging quality control requirements.
The unit has been designed with a large colour screen, lithium battery and large SD memory to drive an easy-to-use interface. The Oxygen Analyser swiftly and precisely measures the O2 and O2 content of gas flushed food packaging (Modified Atmosphere Packaging. No software is required, results can be stored on the Map-Pak device or can be downloaded to a computer as a CSV (Excel) file using the USB cable provided. Alternatively, a separate, low- cost Bluetooth portable printer is available.
The easily programmable “Product Profile” feature incorporates all the important information and control features required and is comprised of the following editable parameters for each product: Customer Name, Product Name, Weight, O2 Alarms (High & Low), Gas Volume Setting.

Glove Box Analysis Calibration & Calibration Interface
The Analyser requires an annual calibration only. There is an Ambient Calibration function available to the user to check the calibration using an air sample (O2 being 20.9% typically). The Calibration Interface can be used for checking the accuracy of the unit against a certified and known gas mixture. Using 1/8” Tubing from the gas regulator fitted to the gas cylinder can be connected and tightened to the ‘Sample In’ fitting provided on the calibration interface. The unit provides the correct flow and filtration required for performing these calibration functions and also serves as an additional Quality Control check for the gases used in the food packaging processes.
Principle Of Operation
Gas Analyser is using a small gas sample from the gas flushed pack, measures, and records levels of Oxygen (O2). The levels of gas are measured using specially customised sensors; Oxygen levels are measured by an electrochemical sensor and the Carbon Dioxide levels are measured by a nondispersive infrared sensor (NDIR). An electric pump automatically draws the gas sample from the food packaging via the sample probe into the sensor array. The O2 and CO2 particles are detected by the respective sensors and the measurements are displayed on the screen within seconds. The N2 level is then displayed as a balance gas reading.
