Zirconia In-Situ Oxygen Analyzer for High-Temperature Combustion Control

ABB’s Zirconia In-Situ Oxygen Analyzers provide accurate, real-time oxygen measurement directly inside stacks and ducts. For full specifications, refer to the ABB Zirconia analyzer page. By eliminating sample conditioning systems, these analyzers reduce maintenance, improve response time, and ensure measurements reflect true combustion conditions at the point of measurement.

Direct In-Situ Measurement for Faster, More Accurate Control

Installed directly in the process, these analyzers deliver immediate oxygen readings that enable operators to optimize air-fuel ratios, increase efficiency, and reduce emissions. The zirconia sensing element provides stable, high-temperature performance with fast response and long service life.

For applications requiring extractive, multi-component gas analysis alongside oxygen, the AO2000 Continuous Gas Analyzer System provides complementary measurement capability.

Designed for Harsh Industrial Environments

The AZ10, AZ20, AZ25, AZ30, and AZ40 models are built to perform in challenging conditions including high dust loading, pressure variations, and temperatures up to 1600°C. The AZ30 and AZ40 models also support dual-sensor configurations and SIL2 capability for safety-critical applications.

For simpler or cost-sensitive oxygen monitoring where in-situ installation is not required, the EasyLine Gas Analyzers offer an alternative approach using extractive measurement methods.

Reliable Performance for Combustion Applications

These analyzers are widely used in boilers, furnaces, kilns, and process heaters across power generation, cement, steel, refining, and petrochemical industries. Their real-time output enables improved combustion efficiency, reduced excess air, and compliance with environmental regulations.

Low-Maintenance and Long-Term Operation

With built-in diagnostics, long-life zirconia sensors, and optional digital communications (HART, PROFIBUS, Modbus), these analyzers integrate seamlessly into plant control systems. Reduced calibration requirements and robust construction help minimize downtime and lower total cost of ownership.

By combining proven zirconia sensing technology with rugged industrial design, ABB’s Zirconia In-Situ Oxygen Analyzers deliver dependable, long-term performance for combustion gas analysis.
