An oxygen analyzer, also known as an oxygen sensor or oxygen meter, is a device used to measure the concentration of oxygen in a gas mixture. It is widely used in various industries and applications where monitoring and controlling oxygen levels are critical.
Oxygen analyzers utilize different technologies to measure oxygen concentration. Some common types of oxygen analyzers include:
- Paramagnetic Analyzers: These analyzers use the paramagnetic property of oxygen to measure its concentration. A magnetic field is applied to a sample gas containing oxygen, and the change in the magnetic susceptibility is proportional to the oxygen concentration.
- Electrochemical Analyzers: Electrochemical oxygen analyzers use a sensing electrode and a reference electrode immersed in an electrolyte solution. The oxygen in the gas diffuses through a gas-permeable membrane and interacts with the sensing electrode, generating an electrical current that is proportional to the oxygen concentration.

- Zirconia Analyzers: Zirconia-based analyzers utilize the principle of oxygen diffusion through a zirconia ceramic sensor. At high temperatures, the zirconia conducts oxygen ions, and a potential difference is generated across the sensor. The magnitude of the potential difference is proportional to the oxygen concentration.
- Infrared Analyzers: Infrared analyzers measure oxygen concentration based on the principle that oxygen absorbs specific wavelengths of infrared light. They use an infrared light source and a detector to determine the amount of oxygen present by measuring the absorption of infrared light.
Oxygen analyzers are used in a wide range of applications, including industrial processes, combustion control, environmental monitoring, medical equipment, diving, and aerospace. They play a crucial role in ensuring safety, maintaining quality, and optimizing performance in various industries where accurate oxygen measurements are necessary.
