Zirconia Oxygen Sensors for Boiler Combustion Efficiency

Improve Boiler Combustion Efficiency with Zirconia Oxygen Sensors

Our zirconia oxygen sensors can help customers optimise their combustion efficiency within the oil, coal, gas and biomass boiler market.

The oxygen to fuel ratio effects boiler efficiency. Too little oxygen results in incomplete combustion creating harmful emissions.

Setting the boiler to burn with excess oxygen is the normal solution to reduce emissions but is very inefficient.

SST Sensing’s oxygen sensors allow the excess oxygen to be reduced whilst still maintaining safe operation.

This saves both money and the environment.

SST Sensing zirconia oxygen sensors have been used to provide a clean burn and reduce harmful emissions in combustion processes for over 25 years.

The oxygen sensors is inserted into the boiler flue to monitor the oxygen level enabling complete control over the boilers air to fuel ratio.

The oxygen sensors come stand alone or with integrated electronics offering digital or analogue industry standard outputs.

Why use SST’s Zirconia Oxygen Sensors?

Their long life comes from their non depleting sensor cell technology. No reference gas is required and easy single point calibration can be performed in fresh air.

The oxygen sensors ability to function in combustion processes with extreme operating temperatures results in a rugged, robust and reliable solution.

No matter where you are in the world, our engineers can work with you to help find the right oxygen sensing solution.

Zirconia Oxygen Sensor System

Zirconia Oxygen Sensor System

The Zirconia Oxygen Sensor System offers a complete solution, removing the need for customers to develop their own electronics. Frequently used in combustion control systems, burning coal, oil, gas and biomass and in oxygen generation systems.

OXY-Flex Oxygen Analyser

OXY-FLEX Oxygen Analyser

The OXY-Flex Oxygen Analyser is suitable for measuring oxygen closed systems, such as ventilation pipes and boiler exhaust flues.


OXY-LC Interface Electronics

The OXY-LC Oxygen Sensor Interface Electronics provides the necessary electronics to power and control SST’s range of zirconium dioxide (ZrO₂) sensors.

Probe Zirconia Oxygen Sensors


The Probe Range of zirconium dioxide oxygen sensors are available in three lengths. Suitable for aggressive and polluted applications such as boiler exhausts. Longer probes are an ideal solution for thicker walled, insulated flue pipes.
