It is portable type, it is powered by Li- ion battery and can be used without AC power supply. It is used for measurement of the concentration of CO ,CO2 and O2 in sample gases simultaneously, calculating combustion efficiency and Lambda. It is based on the single source two beams non-dispersion infrared (NDIR) method for CO ,CO2,fuel cell method (ECD) for O2.

• Based on Innovative NDIR technology.
• Able to measure CO,CO2 and O2 gases, and gas temperature simultaneously.
• Real time calculate excess air coefficient.
• Built-in sampling pump.
• Auto air zeroing.
• Touch Screen.
• USB and RS232 output.
• Optional extensible to measure pressure difference, calculating combustion efficiency, gas velocity, gas flow.
• Data logging software available.
• Simple pretreatment device(optional).

Boiler, furnace exhaust emission gas and combustion efficiency control.
