Paramagnetic Analyzers

Definition

Paramagnetic analyzers are instruments used to measure the concentration of gases, particularly oxygen, based on their magnetic properties. These analyzers utilize the principle that paramagnetic gases, such as O$_2$, are attracted to magnetic fields, allowing for precise detection and quantification in combustion environments. Their ability to provide real-time data makes them essential for monitoring combustion processes and optimizing efficiency.
