GA5000 Gas Analyser

GA5000 Gas Analyser

The GA5000 is an ATEX portable gas analyser for the landfill gas market.



Easy to use and calibrate, the GA5000 benefits from its market leading reliability and helps you standardize your monitoring routines, while complying with environmental legislation.

Built for the landfill gas market, the GA5000 is safe, reliable, and ATEX, IECEx, MCERTS, CSA, and UKAS (ISO17025) certified. The GA5000 is used to measure critical gases such as% CH4, CO2 and O2, H2S (up to 10,000 ppm), NH3, H2, and CO (H2 compensated).

It has been specifically designed to obtain accurate readings of +/- 0.5% after calibration for CH4 and CO2 (+/- 1% O2).

Optional Gas Analyzer Manager (GAM) software is available to allow users to maximize the performance of the GA5000. It has a simple upload and download function and is fully compatible with the latest Microsoft ™ operating systems. Its new and improved firmware update tool lets you skip answers to numerical questions and specify data logging intervals as low as 15 seconds. In addition to this, the check gas screen now provides information on cylinder pressure to avoid analyzer damage and costly repairs. And it comes with a 3-year warranty.

The GA5000 is lightweight and easy to transport. The kit has been developed for customers around the world and presents menus, support materials and instructional videos in a multilingual format.

  • Allows you to plan your next gas monitoring route.
  • 3-axis compass: exact latitude, longitude and altitude ensure accuracy.
  • Clear visualization of the current location and the identification of the closest or closest well.
  • Localization of 2000 IDs at multiple sites in a single analyser.

Good use guide

How do I get the best out of my analyser?

  • Make sure to fully charge the analyser when the battery is discharged – turn off the analyser before starting to charge
  • Perform regular user zero calibrations, this will keep your analysers at optimum precision and will not affect factory calibration
  • Store your analyser in a warm, dry place when not in use.
  • If the analyser gets wet, remove it from the soft case to dry
  • Check and replace filters regularly and bring spares for when you are on site
  • Although robust, your analyser is still scientific equipment and must be treated with care.
  • Regular air purges between readings and at the end of your monitoring will prolong the life of the analyser’s electrochemical cells; We recommend a minimum of 30 seconds
  • If you are using a G100 / G110 / G150, don’t worry if you have to adjust the flow fault setting, this is simply to make it fit your new environment properly.
