Flexible Online UV DOAS Biogas Monitoring System 500ppm ~ 5000ppm

Portable Infrared Biogas Analyzer

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, minimized the investment for users and optimized the biogas monitoring process.

• Unique technology of UV-DOAS, NDIR and ECD combination.
• High & low range H2S measurement, switchable for points before and after scrubber.
• UV-DOAS H2S sensor with higher precision and longer lifespan.
• Continuous monitoring on CH4, CO2, H2S, O2 for optimized process control.
• Modular sensor design enables easy calibration and maintenance.
• Flexible gas conditioning configuration customizable to site requirements.
• Stainless steel protective cabinet to avoid corrosion in long term operation.
• Optional Ex-proof design applicable to safe or hazardous area.
