ABB AZ Series Oxygen Analysers

he ABB AZ Series Oxygen Analysers are a range of high-performance zirconia-based oxygen measurement systems designed to provide continuous, accurate oxygen monitoring in industrial combustion and process applications. Built on ABB's proven oxygen sensing technology, the AZ Series helps operators optimize combustion efficiency, reduce fuel consumption, lower emissions, and improve overall plant performance.

From power generation and waste incineration to cement, metals, and chemical processing, the AZ Series delivers reliable oxygen measurement in some of the world's most demanding industrial environments.

Accurate oxygen measurement is critical for efficient combustion control. Too much excess air reduces thermal efficiency and increases fuel costs, while insufficient oxygen can lead to incomplete combustion, increased carbon monoxide formation, and elevated emissions.

The ABB AZ Series provides real-time oxygen measurements that enable operators to maintain optimum air-to-fuel ratios, helping to:

• Improve combustion efficiency
• Reduce fuel consumption
• Lower CO₂ emissions
• Minimize carbon monoxide formation
• Enhance process stability
• Extend equipment life
• Support environmental compliance
