Combustion analyzer with digital I/O port.

Do any manufacturers make a reasonably priced (< $1K) combustion analyzer for #2 residential with a digital IO port (usb, serial, wifi, Bluetooth, etc.)?. I wish to use this for a boiler monitoring system I am working on in order to start analysis and send results to a data acquisition system.

    Maybe look into just the sensors and cypher up the analysis yourself? IIRC it's an O2 or a CO2 sensor, and two temps.

    Looks like you've already got the flue temp, just need the combustion air temp & either the O2 or CO2 from the flue gas.

    NEVER use C02

    WHy not? Don't some combustion analyzers use CO2 instead of O2?

    Except ALWAYS use CO2, per MFG specs

    Bacharach Intech allows you to download data into you I-phone but only one at a time. Not sure how long you are conducting the test? To datalog for more than 15-20 minutes would take special sensors and sampling assemblies.
    CO2 varies based on the current btu content of the fuel. CO2 readings can be misleading. All fuels produce close to 100% of their CO2 value, whatever it is. O2 determines how much it is diluted, O2 is always 20.9%. Analyzers that calculate CO2 use 11.7% or 11.8% as there guideline, but this does not apply to the actual btus of the fuel.

    I don't know of any analyzers that measure CO2. Most if not all measure O2 and CO then calc the CO2. I really don't understand why boiler manufactures specify CO2 readings, no one is actually taking them.

    Huh. I thought most used one type of sensor & a few used the other.
