Details: A professional residential combustion analyzer + handheld pump with O2 & CO sensors made in the UK. 32-bit microprocessor, color screen, real-time graphing, and alarm-logging. Ideal for HVAC professionals, contractors, or maintenance engineers for residential boilers, heaters, and furnaces. The display screen shows CO, O2, COAF (CO air-free), and EA (Excess Air). The detector can also be used as (1) an ambient detector for general air quality measurements (2) a spot detector or (3) a combustion and flue gas analyzer. Please note, this analyzer does NOT detect flue temperature or calculate combustion efficiency.

Included: Aluminum case, analyzer containing CO and O2 sensors, niobium magnet for mounting on appliances, electronic pump, stainless probe, hose assembly, 3 feet of high temp silicone tubing, water trap, particle filter, NOx filter, sensor cap,sScrew to mount sensor cap to the analyzer, USB charging cable, USB charger, calibration certificate, clear English manual, and instructions.
