Testo 327 Flue Gas Analyser Calibration

(FGA’s less than 6 years old fitted with standard O2 & CO sensors only)

Calibration Process 6 Steps

How Testo 327-1 calibration pricing works:

Year 1 and 2: £119 + VAT
Year 3: £159 + VAT
Year 4 and 5: 119 + VAT
Year 6 or older: Quotation

If your Testo 310 / 320 / 320B or 327 is overdue its service, then a £75 + VAT late service fee may apply in addition to the standard calibration cost of £119 + VAT or £159 + VAT, depending on which service has been missed.

For units that are over 6 years or older, the cost for calibration would be quoted upon inspection of the unit. You would be quoted the cost before calibration is undertaken.

Service includes the following:

  • Annual Analyser Health Check
  • Calibration certificate including gas sensors, temperature and pressure.
  • Replacement O2 or CO sensor when required.
  • Collection and Delivery

All gas installations must be installed and maintained properly. Gas engineers depend on their instruments performing correctly and providing dependable measurements. These instruments must be maintained and calibrated in accordance with the manufacturer’s requirements.

Test4Less is approved by Anton, TPI & Testo to calibrate their flue gas analysers. We only use genuine OEM parts as supplied to us directly by the manufacturer.

Test4Less is equipped to provide an unbeatable and complete calibration service for all of these instruments as follows:

  • All calibration is carried out on UKAS-calibrated test equipment ensuring traceability and providing the highest-confidence calibration.
