1. A gas analyzer system comprising:

  • a plurality of remote sensor units attachable to one more flues;

    a hand held unit in communication with the plurality of remote sensor units; and

    a host computer in communications with the plurality of remote sensor units,wherein each remote sensor unit comprises;

    a housing;

    an elongated sampling tube extending from the housing and configured to have one end pass through a wall of a flue into a bore of the flue;

    a pump having an inlet and an outlet, the inlet disposed at the other end of the sampling tube for drawing a sample of cumbustion gas from the flue into the housing;

    one or more gas sensors in fluid communication with the outlet of the pump, said one or more gas sensors configured to sense a presence of one or more gases in the combustion gas and to measure a concentration of the one or more gases in the combustion gas;

    a temperature sensor for sensing a temperature of the sample of combustion gas; and

    a wireless transceiver coupled to receive measurement data obtained by the one or more gas sensors and the temperature sensor for sending signals representative of temperature, types of gases, and concentrations of gases to both the hand held unit and the host computer and to receive control signals, from both the hand held unit and the host computer;

    wherein the hand held unit comprises;

    a wireless transceiver for receiving signals representative of temperature, types of gases, and concentrations of gases from the remote sensor units and for transmitting control signals to one or more of remote sensor units; and

    a display that shows the temperature, types of gases, and concentrations of gases;

    wherein circuitry and software disposed in one or both of the remote sensor units and the hand held unit, in operation, process output signals of the one or more gas sensors and the temperature sensor;

    wherein the host computer comprises;

    a wireless transceiver for receiving signals representative of temperature, types of gases, and concentrations of gases from the remote sensor units and for transmitting control signals to one or more of the remote sensor units;

    a display that shows the temperature, types of gases, and concentration of gases; and

    circuitry and software that, in operation, process signals received from the remote sensor units and send control signals to one or more of the remote sensor units; and

    wherein at least one remote sensor unit wirelessly sends signals representative of temperature, types of gases, and concentration of gases in a flue to the hand held unit which allows a technician operating the hand held unit to make adjustments to a fuel intake and/or air intake of a burner coupled to the respective flue, and also wirelessly sends signals representative of temperature, types of gases, and concentration of gases in the flue to the host computer for review by an analyst reviewing combustion information in the respective flue and other flues that exhaust gas from other burners.
