Oxygen & COe Analyzer

Oxygen & COe Analyzer for Combustibles

Ideal for process control, flare safety control, and combustion control

In situ, real-time readings for optimal fuel efficiency of boilers, furnaces, and kilns, with fast and simple service ability, and all at a tremendous value. Our COSA XENTAUR™ O2CX Oxygen and COe Analyzer is the ideal choice to optimize fuel efficiency on most combustion sources and for stack oxygen applications. It has several significant advantages over other oxygen transmitters. The addition of our unique combustible sensor allows the process to safely operate with a lower Excess Air ratio, which translates into higher fuel efficiencies.

Our O2CX Oxygen and COe Analyzer offers great accuracy and sensitivity below 10% oxygen and does not require dilution air like other competitors utilizing a Pellistor sensor.

For easy access and service, the flow guidance tube design allows the sensors to be located near the back of the transmitter. This makes for simple service without the need to remove the entire assembly from the stack and struggle with removing sensors located at the end of the probe.  Easily remove or replace O2 and COe sensors – saves time and $$.

It is versatile for different mounting requirements or difficult applications like high temperature, dust, or even hazardous installations, and it can also be outfitted with auto calibration. It provides all of this and is the best value available on the market today to measure oxygen and carbon monoxide equivalent (COe).

The O2CX combines superior sensors with a robust to deliver better combustion performance, trouble-free operation, and simple serviceability for safe, reliable and efficient industrial combustion measurement.


  • High Accuracy: Uses advanced electrochemical sensors to measure oxygen and carbon monoxide concentrations with high accuracy and precision. This ensures that process parameters are accurately monitored, leading to improved process efficiency and reduced emissions.
  • Wide Range: Can measure oxygen concentrations in the range of 0-25% and carbon monoxide concentrations in the range of 0-500 ppm. This wide range makes the analyzer suitable for use in a variety of industrial applications.
  • Fast Response Time: Has a fast response time of less than 10 seconds. This allows operators to quickly detect and respond to changes in process parameters.
  • Easy to Use: Is designed to be easy to use, with an intuitive interface and simple menu navigation. This makes it easy for operators to set up and use the analyzer, even without extensive training.
  • Durable and Reliable: Built to withstand harsh industrial environments, with a rugged design that can withstand temperature and humidity fluctuations. This ensures that the analyzer provides accurate and reliable measurements even in challenging conditions.
  • Low Maintenance: Requires minimal maintenance, with long-lasting sensors and an easy-to-replace filter. This reduces downtime and ensures that the analyzer is always available when needed.


Here are some of the industries that use the O2CX Oxygen and COe Analyzer:

  • Power Generation: Used in power generation plants to measure the oxygen concentration in the flue gas. This information is used to optimize the combustion process and to reduce emissions.
  • Industrial Combustion: Used in industrial combustion processes to measure the oxygen concentration and to control the fuel-to-air ratio. This helps to improve process efficiency and to reduce emissions.
  • Petrochemical: Used in the petrochemical industry to measure the oxygen and carbon monoxide concentrations in process streams. This helps to ensure that the process is operating optimally and that product quality is consistent.
  • Environmental Monitoring: Used in environmental monitoring applications to measure the oxygen and carbon monoxide concentrations in the air. This information is used to monitor air quality and to identify sources of pollution.
  • Steel Industry: Used in the steel industry to measure the oxygen concentration in the furnace atmosphere. This information is used to optimize the steel-making process and to reduce energy consumption.
