SO2 Analyzer (Ei300)
High performance sulfur dioxide analyzer with the latest UVA technology

Using the proven Ultraviolet Absorption Spectrometry (UVA) 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.
