testo 327 - Flue Gas Analyser (advanced kit + gas leak detector)

Image
The testo 327 Advanced Kit + Gas Leak Detector is a professional combustion and gas safety package for heating engineers working on domestic and light commercial systems. It combines accurate flue gas analysis with gas leak detection to improve service efficiency and safety checks. It is suited to boiler servicing and commissioning, gas leak detection, combustion checks, CO safety testing and performance diagnostics.
  • Advanced Kit + Gas Leak Detector - including analyser, probe, testo IR Printer, 2x temperature clamp probes, gas leak detector, case, and power supply.
  • Reliable Gas Detection - quickly identify leaks with visual, audible, vibration alerts for enhanced safety.

The testo 327 Advanced Kit + Gas Leak Detector combines advanced flue gas analysis with gas leak detection for professional boiler servicing and safety checks.

How to Combine Advanced Combustion Testing with Leak Detection

When engineers need to assess both appliance performance and gas installation safety, this kit keeps two essential tools together. The testo 327 Advanced Kit supports detailed combustion checks, while the gas leak detector helps locate possible leaks around pipework, joints, fittings, valves, meters, and appliance connections.
This is useful during annual servicing, new boiler commissioning, repair work, and post-maintenance safety checks. Engineers can test combustion, check efficiency, investigate CO levels, and then verify surrounding gas connections during the same visit.
The combined setup helps improve workflow and reduces unnecessary tool changes.

Why Leak Detection Adds Value to Boiler Diagnostics

Combustion analysis shows how well the boiler is burning fuel, but it does not check every possible gas escape point. Adding a gas leak detector helps engineers assess the wider installation as well as the appliance.

This kit supports:
  • Advanced flue gas analysis: CO, O₂, flue gas temperature, efficiency, CO₂, and excess air.
  • Gas leak detection: Checks around joints, valves, unions, meters, and appliance connections.
  • Fault investigation: Helps identify poor combustion, suspected leaks, and post-repair risks.
  • Real-world application: After replacing a component, engineers can retest combustion and check nearby gas fittings before completing the job.

Solving Safety Risks During Servicing and Repairs

Gas safety risks can come from both poor combustion and leaks in the installation. This bundle helps engineers check both areas as part of one structured workflow.
The analyser helps detect combustion faults such as high CO or poor efficiency. The gas leak detector helps identify possible gas escape risks that may not be visible during a standard visual inspection.
These checks support professional safety workflows and link naturally with BS 7967 guidance, gas safety testing, and routine boiler maintenance standards.

Streamlining the Engineer’s Toolkit

Keeping combustion analysis and leak detection together helps engineers work more efficiently. The kit can be supported with Testo flue gas probes, replacement filters, printer options, calibration services, and gas leak detector accessories.
It also connects well with gas pressure kits, differential pressure meters, temperature probes, and wider HVAC diagnostic tools.
