Calibration Unit For Zirconia Oxygen Analyzer

The Zirconia Oxygen Analyzer is used to monitor and control the oxygen concentration in combustion gases, in boilers and industrial furnaces, for wide application in industries which consume considerable energy–such as steel, electric power, oil and petrochemical, ceramics, paper and pulp, food, or textiles, as well as incinerators and medium/small boilers. It can help conserve energy in these industries.

It also contributes to the preservation of the earth’s environment in preventing global warming and air pollution by controlling complete combustion to reduce CO2, SOx, and NOx. Axis is providing system solutions for high availability, reliable, accurate with sampling system design where analytical measurement demands it.

The Axis Zirconia Analyzer calibration unit is designed for the calibration process which is available with a fully automatic & manual option. Choose the detector version which best suits your needs so that an optimal combustion control system can be obtained.

The system configuration can be classified into below basic patterns as follows:


  • This system is for monitoring and controlling oxygen concentration in the combustion gases of a large-size boiler or heating furnace. Clean (dry) air (21%O2) is used as the reference gas and the span gas for calibration. Zero gas is fed in from a cylinder during calibration. The gas flow is controlled by the flow setting unit with the manually setting of the ball valve.


  • System 2 uses the automatic calibration unit, with auto-switching of the calibration gas. In this System, the gas flow is controlled by the solenoid valve, which is powered by an electronic signal from the converter according to the Sensor output.
