Gas analyzers are instruments used to measure the concentration of various gases in a mixture. They are essential in many fields, including environmental monitoring, industrial processes, and safety applications. By providing real-time data on gas composition, these devices help ensure compliance with regulations and improve air quality. There are different types of gas analyzers, such as infrared analyzers, electrochemical sensors, and mass spectrometers. Each type operates on specific principles to detect gases like carbon dioxide, oxygen, and nitrogen oxides. These tools are crucial for maintaining safe working environments and understanding atmospheric conditions.
