Product Introduction

he model M7873 Oxygen Analyzer is a Zirconia analyser designed for the analysis of combustion gases. It measures the residual concentration of Oxygen in the fumes produced by combustion processes, that is the quantity of residual Oxygen after the complete oxidation of the fuel.


Product Application

  • Combustion efficiency control in every type of boilers, ovens and furnaces
  • Electric power industry
  • Coal fired power plants
  • Chemical and petrochemical industry
  • Flue gas
  • Glove boxes
  • Inertizing circuits with not-combustible gases
  • In general, control of residual Oxygen in every combustion process


  • Real in situ measurement with the sensor placed on the tip of the probe
  • Direct insertion into the chimney
  • Selected material to resist the attack of corrosive substances that may develop in the process
  • No reference flow needed
  • Extremely fast response time and excellent stability
  • Possibility to perform periodical calibration directly in situ, without dismantle the probe from process
