Flue Gas Analysers: A Buyers Guide To Calibration & Servicing

If you’re shopping for a new flue gas analyser, it’s prudent to consider the cost of mandatory annual calibration/servicing throughout the life of your new instrument. 

With various manufacturers each offering their own calibration costs, gas sensor replacement intervals and quantity of UK-approved service centres, it’s a minefield comparing the cost of ownership of one analyser against that of another. 

Therefore, we feel a one-stop guide that summarises each manufacturer will be a valuable asset in your choice of new analyser. In alphabetical order below, we list what you can expect to pay, locations of service centres and other points to consider when organising annual calibration and recertification with each manufacturer.

Additional Things To Note

  • Anton analysers feature on-screen reminders of re-calibration 30 days before the due date. If this is subsequently ignored, the analyser will lock off as a safety procedure until re-calibration has been completed.
  • Additional charges may be made if an analyser is booked on the wrong service (for example, booking stating years 1-4 if it requires a 5th-year service), if an analyser misses a year and is sent the following year, and if non-warranty defects are discovered during the service that requires additional parts/labour to rectify.

It pays to explore what is offered by each flue gas analyser manufacturer. Although the cost of calibration will likely feature high on the agenda, it certainly shouldn’t be all that is considered:

  • Are there regional service centres available if you don’t want the hassle of posting?
  • How quickly can a manufacturer service and recertify your analyser? You’ll likely need to plan your work around this.
  • How easy can each manufacturer make the service and re-certification process for you?
