Details: A basic and affordable Residential Combustion Analyzer + Handheld Pump with high quality O2 and CO sensors. We developed this unit for HVAC professionals, contractors or maintenance engineers for residential boilers, heaters or furnaces. The display screen shows CO, O2, COAF (CO air-free) and EA (Excess Air %). The detector can also be used as a ambient detector for general air quality measurements or can be plugged up to the hand pump to function as spot detector or Combustion and Flue Gas Analyzer. Please note, this analyzer does NOT detect flue temperature nor calculate combustion efficiency. Simple large LCD and with backlight.
