  1. It is not necessary to self-certify an anemometer: the certified analyser validates the results.
  2. Ensures quality reporting and analysis: BIOGAS 5000 supports your analysis by providing consistent and reliable data collection.
  3. The BIOGAS 5000 features Geotech’s “best-in-class” infrared bench technology.
  4. Adheres to strict compliance with PPC (Pollution Prevention and Control)
  5. Configure the BIOGAS 5000 specifically for your company’s unique specification.
  6. The analyser supports the efficiency of your digestion process, providing you with information so you can change gas levels for optimal performance.
  7. Provides peace of mind that your desulfurization process is working properly by measuring desulfurization levels before and after.
  8. Allows you to monitor the efficiency of your engine and its useful life by monitoring sulphur levels.


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.
