Map-Pak 2 is the next generation of Modified Atmospheric Packaging gas analyser from AGC Instruments. The Map-Pak 2 Combi measures the Oxygen, Carbon Dioxide and Nitrogen content in gas flushed food packages (the latter being as a balance gas). Designed specifically for the Food Industry, it has been completely redesigned with a new large colour Touch Screen, Lithium Battery, and Large SD memory to drive an easy-to-use User Interface.
With a faster CO2 sensor complimenting the industry-leading O2 sensor, the Map-Pak 2 gas analyser swiftly and precisely measures the O2/CO2 content of gas flushed food packaging (Modified Atmosphere Packaging).

The Map-Pak 2 was developed as a quality control device with a wide range of features that 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 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 and CO2 Alarms (High & Low)
- Gas Volume Setting
These lightweight portable analysers are easy to use in quality control functions and can be used for all food applications, as well as some applications in the pharmaceutical industry. Sample measurements and results are achieved within 20 seconds and the operator can modify the various features of the analyser to best suit their requirements. A minimal gas sample is required, and three sample volume options are available to suit all packaging types. Long battery life also ensures continuous operations in busy production schedules.
The probe holder has now been integrated into the unit for ease of use and storage as well as safely covering the needle when not in use. Strengthened and wipe-clean materials are used in an ergonomic design for weight reduction and increased comfort for the operator. There are also features such as the new internal Filter and external Hydrophobic Filter to protect the analyser sensor array which saves on maintenance costs. The new modular probe also allows for the easy replacement of parts by the end-user. Furthermore, no software is required to download the results to a PC which is done via the dual-use USB cable provided for charging and data transfer.
Typical Applications
- Meat and Poultry
- Seafood
- Pre-cooked Meats
- Dairy Produce
- Fruits & Vegetables
- Convenience Foods
- Baked Goods
- Salads
- Pasta
- Coffee
- Pharmaceuticals
- Glove Box Analysis
Results and Reporting
Results can be stored on the Map-Pak device and can be downloaded to a computer as a CSV (Excel) file using the USB cable provided. Furthermore, a small portable printer is available for the Map-Pak range to print results on receipt-size paper or labels. The Map-Pak 2 communicates wirelessly via Bluetooth® with this compact printer using special thermal paper which means that no ink cartridges are used, thereby cutting down on costs. The fast print speed ensures that results are printed promptly for your record-keeping needs with a fine cutter to separate the records easily. Each of these reporting options allows the user to display their results in a way that best suits their HACCP system. Furthermore, the calibration certificates provided with each Map-Pak unit adheres to the Modified Atmosphere Packaging and HACCP requirements for audits.
Calibration & Calibration Interface
The Map-Pak 2 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 Map-Pak 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 process.

Principle of Operation
The Map-Pak 2, using a small gas sample from the gas flushed pack, measures, and records levels of Oxygen (O2) or Oxygen and Carbon Dioxide (CO2). 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.
Available variation is the Map-Pak O2: measures the O2 content of gas flushed packaging.
