APSA-360A/CU-1 Ambient Hydrogen Sulfide Monitor
Overview
APSA-360A/CU-1 Ambient H2S monitor measure SO2 converted H2S through oxidation catalyst based on Ultra Violet Fluorescence. In order to reduce measurement error by water concentration fluctuation in ambient, humidifier is set at sample line. It enables long-term stability according to stabilizing catalytic reaction.
Features
- Monitor H2S with high sensitivity range in ambient air continuously.
- Set humidifier at sample line to stabilize catalytic reaction.
