testo 327 - Flue Gas Analyser (standard kit + testo gas leak detector + CPA1 kit)

Image
The testo 327 Standard Kit + Gas Leak Detector + CPA1 Kit is a complete flue gas analysis and gas safety testing package for engineers carrying out boiler, appliance and CO safety checks. It supports combustion measurement, leak detection and CPA1-related testing in one practical kit. It is suited to boiler servicing and commissioning, gas leak detection, CPA1 testing and CO safety checks.
  • Standard Kit + Gas Leak Detector + CPA1 Set -  including analyser, probe, gas leak detector, CPA1 set, case, and power supply.
  • Reliable Gas Detection - quickly identify leaks with visual, audible, vibration alerts for enhanced safety.
  • Specialist CO Testing - CPA1 probes enable safe and accurate CO testing on cookers and flueless appliances.

testo 327 Standard Kit + Gas Leak Detector + CPA1 Kit

The testo 327 Standard Kit + Gas Leak Detector + CPA1 Kit is a professional bundle for combustion analysis, gas leak detection, and CPA1-related appliance testing.

How to Complete Combustion, Leak, and CPA1 Checks with One Kit

When engineers need to complete several gas safety and appliance checks during one visit, this bundle helps keep the process organised. The testo 327 supports boiler flue gas analysis, the gas leak detector helps identify potential gas escape risks, and the CPA1 kit supports appliance performance and pressure-related testing tasks.
This is useful for engineers carrying out servicing, commissioning, landlord maintenance, and fault diagnosis. Instead of switching between separate toolsets, engineers can move through each test stage in a logical order.
The kit is especially useful for professionals who want one practical package for everyday gas and heating work.

Why a Complete Testing Workflow Reduces Risk

Gas appliance faults can involve combustion, pressure, ventilation, or installation issues. A single test may not show the full picture, so a combined workflow helps engineers make safer decisions.
The testo 327 checks how well the boiler is burning fuel. The gas leak detector checks accessible pipework and fittings. The CPA1 kit adds support for wider appliance testing requirements.

The bundle supports:
  • 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.
  • CPA1-related testing: Supports appliance performance and pressure-related workflows.
  • Real-world application: During a landlord service visit, engineers can test combustion, check for gas leaks, and complete CPA1-related tasks with one organised kit.

Solving Safety and Compliance Challenges

Incomplete testing can lead to missed faults and repeat visits. This kit helps engineers follow a more complete process, supporting safer servicing and clearer job records.
CO and combustion checks can be linked to guidance such as BS 7967. CPA1-related workflows can also be supported by using the correct pressure and appliance testing equipment as part of a structured service process.

Streamlining Your Professional Toolkit

Keeping essential tools together helps reduce time lost searching for equipment. This kit can be linked with Testo flue gas probes, replacement filters, printer options, calibration services, gas pressure kits, and digital thermometers.

Built for Everyday Gas Engineers

This bundle is designed for engineers who need flexibility across several job types.
  • Combustion testing: Supports boiler safety and efficiency checks.
  • Gas leak detection: Helps identify potential gas escape risks.
  • CPA1 support: Adds capability for appliance testing workflows.
  • Professional kit format: Helps reduce tool changes on site.
