SO2 Analyzer (Ei300)

High performance sulfur dioxide analyzer with the latest UV-DOAS technology

Using the proven Ultraviolet Differential Optical Atomic Absorption (UV-DOAS) measurement principle combined with state of the art electronics and proprietary algorithms, the Ei300 SO2 Analyzer

measures sulfur dioxide by passing an ultraviolet light beam through an adjustable-length sample cell and into a detector. 


The concentration is determined utilizing an algorithm comparing the light energy absorbed by sulfur dioxide molecules during zero, span, and sample modes and correcting for interfering gases.
