  • O₂ and H₂-compensated CO sensor up to 30,000 ppm.

testo 300+ Flue Gas Analyser Advanced Kit

The testo 300+ Advanced Kit is a professional combustion analyser package for engineers who need broader testing capability for boiler servicing and diagnostics.

How to Handle More Detailed Boiler Diagnostics with an Advanced Kit

When engineers work across varied heating systems, a more complete analyser kit helps reduce delays on site. The testo 300+ Advanced Kit supports flue gas analysis, commissioning, burner adjustment, and fault diagnosis with a stronger professional setup than a basic kit.
The advanced kit format helps engineers arrive prepared for more complex service tasks. This is useful across domestic boilers, commercial heating systems, and plant room environments where more detailed combustion checks may be required.
Clear readings help engineers make practical decisions quickly. Instead of relying on symptoms alone, they can measure appliance performance and confirm whether adjustments have solved the issue.

Why Advanced Combustion Testing Prevents Repeat Callouts

Repeat boiler faults often come from incomplete combustion checks, poor air supply, or incorrect burner setup. The testo 300+ Advanced Kit helps engineers identify these causes with reliable flue gas measurement.

Key testing benefits include:

  • CO measurement: Helps identify incomplete combustion and safety risks.
  • O₂ measurement: Supports air-to-fuel ratio checks.
  • Flue gas temperature: Helps assess appliance performance.
  • Draught and pressure support: Useful for flue and system diagnostics.
  • Efficiency calculations: Helps demonstrate improved boiler performance.
  • Real-world application: If a commercial boiler shows poor efficiency, engineers can test combustion, adjust the burner, and retest before completing the job.

Solving Safety and Efficiency Problems on Site

Unsafe carbon monoxide levels and inefficient fuel use can be costly for customers and dangerous for occupants. The testo 300+ Advanced Kit helps engineers detect these problems during servicing, commissioning, and maintenance.
Calculated values such as CO₂, excess air, and efficiency make results easier to interpret. This supports clearer communication with customers, facilities teams, and maintenance managers.

Streamlining Professional Test Equipment

The testo 300+ Advanced Kit can be supported with compatible Testo flue gas probes, replacement filters, printer options, calibration services, protective cases, and consumables. It also works well with gas leak detectors, gas pressure kits, differential pressure meters, and digital thermometers.
