Description

Use the Gas Ratio Calculator to process the results from your Gas Flue Analyser and find the CO/CO2 ratio for natural gas.

If the boiler is running efficiently there may be no need to service it. Simply test the boiler with your analyser and obtain the oxygen, carbon monoxide and carbon dioxide values. Input the values from the analyser into the Gas Ratio Calculator, the CO/CO2 ratio will be calculated and advice also given on whether the boiler should be serviced or not.

Once you have your results you can email them directly from within the app, save them to your device or export them to another app that supports text files, such as Dropbox, Google Drive or Evernote.
