SOx Analysis

Ambient Hydrogen Sulfide Monitor

APSA-370/CU-1 Ambient H2S monitor measures SO2 converted H2S through oxidation catalyst based on Ultra Violet Fluorescence. In order to reduce measurement error by water concentration fluctuatin in ambient, humidifier is set at sample line. It enables long-term stability according to stabilizing catalytic reaction.

• Monitor H2S with high sensitivity range in ambient air continuously.
• Set humidifier at sample line to satbilize catalytic reaction.
