Paramagnetic analyzers are instruments used to measure the concentration of gases, particularly oxygen, in various environments. They operate based on the principle that paramagnetic gases, like oxygen, are attracted to magnetic fields. This property allows the analyzer to detect changes in gas concentration by measuring the magnetic susceptibility of the sample. These analyzers are commonly used in industries such as environmental monitoring, medical applications, and industrial processes. They provide accurate and real-time measurements, making them essential for ensuring safety and efficiency in operations where gas concentrations are critical.
