Product Description

Advanced Flue Gas Analyzer Kit

The Wöhler A 450 (Item 8389) is a professional combustion analyzer configured for reliable residential flue gas analysis, burner tuning, and draft diagnostics. This version includes O₂ and CO measurement (10,000 ppm).

Comprehensive Gas Measurement Capabilities

Measures oxygen (O₂) from 0.0 to 21.0% using an electrochemical sensor, supporting combustion efficiency calculations and air-to-fuel ratio adjustment.
Measures carbon monoxide (CO) from 0 to 10,000 ppm with 1 ppm resolution, enabling detailed burner setup and safety checks.
Uses an electromechanical sensor.

Pressure and Draft Measurement

Measures differential pressure and chimney draft from 0.00 to ±110.00 hPa with 1 Pa resolution, providing a direct way to verify that venting conditions align with appliance requirements. This helps identify draft-related causes of unstable combustion, nuisance lockouts, or inconsistent combustion readings across operating conditions.

Temperature Measurement

Measures flue gas temperature from -20°C to 800°C (-4°F to 1,472°F) with 0.1°C resolution, supporting evaluation of combustion performance and venting conditions through stack temperature trends.
Measures ambient temperature from -20°C to 100°C (-4°F to 212°F) with 0.1°C resolution,providing a consistent reference for calculations and documentation of operating conditions
