Zirconia Oxygen Sensors for Controlled Atmosphere Applications

SST’s Zirconia Oxygen Sensors

SST’s Zirconia Oxygen Sensors help to control or monitor oxygen levels in Controlled Atmosphere Applications

Many applications need a system to control or monitor oxygen levels in an enclosed space. To alert to hazardous oxygen levels, to control to selected levels as part of a critical process or prevent the possibility of combustion occurring an accurate and reliable sensor is needed.

That’s where SST comes in with a wide range of oxygen sensing solutions.

A variety of housing styles, cabling and electrical connections are available. Unlike other technologies, their long operating life is due to the non-depleting sensor cell technology. No reference gas is required and easy single point calibration can be performed in fresh air.

SST’s Zirconia Oxygen Sensors have the ability to function accurately in extreme environmental conditions result in a rugged, robust and reliable sensor that is RoHS compliant.

These sensors can come standalone or with integrated electronics, offering digital or analogue outputs. They are the Oxygen sensing components to your system. Or, SST can provide an intelligent unit to locally control outputs and transmit to a remote monitoring system.

Applications include alarming to dangerous levels of oxygen when storing or handling gases and chemicals. Sustaining low oxygen levels in fire suppression systems for protecting valuable industry equipment – such as servers and archives.

Prolonging the life of perishable products during transportation and storage within Controlled Atmosphere environments.

Or controlling the optimal oxygen level within processes such as composting.

SST can work with the customer on a standard or customised solution for gas monitoring systems.

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 for monitoring and controlling the oxygen in enclosed spaces and combustion applications.

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, controlled atmosphere applications and combustion prevention.


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.
