Model 6400T Sulfur Dioxide Analyzer

SKU: 6400T

The 6400T Series analyzers uses a proven UV fluorescence principle coupled with state-of-the-art microprocessor technology to provide accurate and dependable measurements of low level SO2. The 6400T-H2S measures hydrogen sulfide (H2S) by incorporating a catalytic convert​er set at 600°F (315°C) to oxidize H2S into SO2 while leaving other more difficult to oxidize sulfurs unconverted. A switching mode allows analysis of both H2S and SO2 concurrently.
