The FORENSICS DETECTORS FD-4A-FLUE combustion analyzer measures oxygen (O2) and carbon monoxide (CO), and calculates carbon monoxide air-free (COAF) and excess air (EA). It is used for combustion analysis in residential boilers, heaters and furnaces, as well as for ambient air quality measurements. With the pump and sensor, it can be used as a spot detector or as a combustion and flue gas analyzer.
The large LCD has a backlight, and the electrochemical O2 and CO sensors have a lifespan of 2–3 years. The device does not measure flue gas temperature, calculate combustion efficiency or detect carbon dioxide (CO2). It is not intended for measuring vehicle exhaust gases.
