About Flue Gas Analysers
A flue gas analyser helps heating engineers check how well a boiler is burning fuel. It measures gases in the flue, helping engineers assess performance and spot signs of poor combustion.
Whether you are servicing a boiler or investigating a fault, a gas analyser provides readings to compare with the boiler manufacturer’s guidance. Explore the range at Acutest Direct to find a model suited to your work.
Why Use a Flue Gas Analyser?
Check Boiler Performance
Readings such as oxygen (O2), carbon monoxide (CO) and flue gas temperature help engineers assess how a boiler is running. The measurements available depend on the model.
Improve Efficiency
A gas analyser helps engineers check the balance of air and fuel. The results can guide adjustments, where permitted by the boiler manufacturer, to help reduce wasted fuel.
Find Faults
Unusual readings can highlight a combustion problem. This helps engineers focus their checks and decide what needs further investigation.
Support Safety Checks
Measuring CO in the flue helps engineers assess combustion as part of a full boiler service. Results should be checked against the limits set by the boiler manufacturer.
Keep Clear Records
Some models let you save, print or share readings. These features make it easier to keep service records and show what was checked.
Choosing the Right Gas Analyser
When choosing a flue gas analyser, check that it suits the fuel and type of appliance you work on. Useful features to compare include:
- Measurements: The gases, temperatures and pressures the analyser can measure, including their ranges.
- Ease of use: A clear screen, simple controls and battery life that suits your working day.
- Accessories: The probes, hoses and other items supplied with the analyser or kit.
- Test records: Options for saving results, connecting to an app or using a compatible printer.
- Ongoing costs: Servicing, calibration and replacement parts.
❓ Frequently Asked Questions (FAQ)
Q1: Can I use the same gas analyser for gas and oil boilers?
A. Some models support both gas and oil appliances. Check the supported fuels, measuring ranges and required probes before choosing an analyser or kit.
Q2: Does a flue gas analyser need calibration?
A. Yes. Regular servicing and calibration help keep readings accurate. Follow the analyser manufacturer’s recommended schedule and include these costs when comparing models.
