Obsolete replacement detailed here.

The Kane 452 NO flue gas analyser measures CO (0 to 2000ppm), NO (0-100ppm) and CO2 direct with an infra-red sensor 0-20%.  Differential temperature and differential pressure ±80mbar are measured too, designed for the domestic gas heating engineer for installing and servicing oil or gas boilers. With a kit available inclusive of a smoke pump for oil boiler work.

Operation is by a rotary switch with parameters shown on a six-line display.  A dual pump system for the CO sensor provides over-range protection. The structured automatic commissioning adheres to Technical Bulletin 143 without the user having to select the test sequence.

A data hold feature fixes current results on screen and readings are stored to internal memory. Results can be downloaded wirelessly or sent an infrared printer; both of these features are optional.  The Kane 452 NO can measure combustion efficiency, CO/CO2 ratio, pressure, let by and tightness, commission testing and flue draft.

Suitable for the following fuel types; Natural gas Propane, Butane, LPG, Light Oils (28/35 sec), Wood Pellets, Town Gas, Coke Gas, Bio-Oil, Bio Gas & 5 user-defined fuels.

Tested to EN50379, BS7967 and TB 143.
