OXY-Flex Oxygen Analyzer for Accurate Industrial Oxygen Measurement

Accurate oxygen measurement is important for industrial combustion, process control, and emissions monitoring. Maintaining the correct oxygen concentration improves combustion efficiency, reduces fuel consumption, and supports consistent process performance. 

The OXY-Flex Oxygen Analyzer from SST Sensing is designed to provide continuous oxygen measurement using proven zirconia sensing technology. Suitable for a wide range of industrial applications, it delivers stable readings across varying operating conditions while supporting efficient process control and industrial process automation.

Why oxygen measurement matters 

Many industrial processes rely on precise oxygen control. In combustion systems, incorrect oxygen levels can reduce efficiency, increase fuel consumption, and raise emissions. Continuous monitoring allows operators to optimize the air-to-fuel ratio, improving system performance while helping meet environmental requirements. 

In other applications, including industrial process control and heat treatment, accurate oxygen measurement supports product quality, repeatability, and operational safety. 

Zirconia technology for reliable oxygen analysis 

The OXY-Flex analyzer uses a closed-loop zirconia oxygen sensor to continuously measure oxygen levels from 0.1% to 100%. Unlike electrochemical sensors, zirconia technology is non-depleting, delivering a long service life with stable performance over time. 

The analyzer is designed for demanding industrial environments and provides: 

• Continuous oxygen measurement 
• Fast response to changing oxygen concentrations 
• Stable long-term performance 
• Linear analog output for process integration 
• Built-in diagnostics to support system monitoring 

These features make the analyzer suitable for both new installations and retrofit projects that require dependable oxygen measurement. 

Supporting combustion efficiency 

One of the most common applications for the OXY-Flex Oxy-Flex analyzer is combustion control. Monitoring oxygen levels in flue gases allows combustion systems to operate closer to their optimum air-to-fuel ratio. 

Benefits include: 

• Improved fuel efficiency 
• Reduced excess oxygen 
• Lower operating costs 
• Reduced emissions 
• More stable combustion performance 

Optimizing combustion can also help extend equipment life by reducing unnecessary thermal stress caused by inefficient burner operation.
