Ultraviolet Analyzers

Definition

Ultraviolet analyzers are instruments used to detect and measure the concentration of specific compounds in combustion gases by utilizing ultraviolet light. These devices work by analyzing the absorption of UV light at particular wavelengths, which indicates the presence of various gases, such as nitrogen oxides (NOx) or sulfur dioxide (SO2), in the combustion process. This technology is crucial for real-time monitoring of emissions and ensuring compliance with environmental regulations.
