The K905CONOX handheld analyzer is easy to use for domestic and industrial boiler flue gas measurement and analysis. It operates on all boiler types and can display 8 parameters simultaneously showing measurements and calculations of boiler efficiency and pollution. It measures O2, flue and NETT temperature and calculates CO2, boiler efficiency, excess air and losses. CO is measured with a hydrogen compensated sensor for increased accuracy. The K905 measures CO and calculates CO/CO2 ratio (The Poison Index) to give complete readings for effective boiler analysis and safety.

Includes seven preprogrammed fuels with two positions for user-specified fuels. With 150 memory locations, tests can be stored and downloaded to the optional IR printer through the infrared port or to a PC through the RS-232 port utilizing the optional Fireworks™ software package. The unit comes complete with a large carrying case, probe and battery charger.


  • 0 to 10,000ppm H2 compensated CO sensor
  • Installed memory can store up to 150 readings and can transfer data to a printer or PC (via Infra-red printer link)
  • Printout displays the time/date of each measurement as well as personalized information such as company name and telephone number
  • Long life rechargeable battery & large 4 line display
