Model M7873​​​

Zirconium Oxide Oxygen Analyzer

Oxygen Analyzer on Site with Zirconium Oxide (Temp. Up to 800 ° C)


Model M7873 is a Zirconium Oxide Oxygen analyzer intended for the analysis of combustion products. Measures the concentration of residual oxygen in the fumes produced by combustion processes, Ie the quantity of oxygen left after the complete oxidation of the fuel.


The instrument is characterized by a special Zirconium oxide sensor with reference to the solid state (consisting of a special mixture of metals and their oxides) which avoids the need for a reference air flow.

  • Measure actually on site with sensor on the tip of the probe
  • No need for a reference flow
  • High response speed and excellent stability
  • Possibility to perform calibration directly on site without removing the probe
  • Low installation and maintenance costs
  • Field replaceable probe components
  • Measuring Principle: Zirconium Oxide (Zirconia). Micro-pod sensor technology with no need of reference air
  • Accuracy : 1% O2 below 5% or 2% of reading above 5%
  • Repeatability : ± 1% of reading (short term)
  • Output Resolution : .01% O2
  • Response Time: Sensor:1 sec; Overall system < 5 sec.
  • Flue Gas Temperature : Up to 700°C (on request up to 800°C)
  • Insertion Length : 100 / 200 / 300 mm
  • Boilers using any type of fuel
  • Biomass Plants
  • Furnaces
  • Low Temperature Incinerators
  • Biological Muds Dryers (safety)
  • H2O measurement in drying processes
