Online UV-DOAS Biogas Monitoring System

Gasboard-3500UV
Gasboard-3500UV is the new generation biogas monitoring system that primarily designed based on UV-DOAS technology to measure H2S concentration precisely before and after H2S scrubber, and extended with modular sensor of CH4 (NDIR), CO2(NDIR) and O2 (ECD) to realize online continuously monitoring of biogas quality without purging cycle required.The 2 sampling channels design before and after scrubber enable it to provide an ideal solution to guarantee the H2S scrubber efficiency, protect downstream expensive equipment from the damage of overload H2S, minimize the investment for users and optimize the biogas monitoring process.
