Product Overview
KGD - MQ - 527 Online Biogas Monitoring System
The KGD-MQ-527 is a next-generation biogas monitoring system that combines multiple advanced gas analysis technologies for comprehensive biogas component measurement. It utilizes:
UV-DOAS technology for accurate H2S concentration measurement before and after desulfurization
NDIR technology for CH4 and CO2 concentration measurement
ECD method for O2 concentration measurement
The system features dual sampling channels for real-time H2S monitoring before and after scrubbers, protecting downstream equipment from excessive H2S damage. Its modular design makes it suitable for various biogas applications while minimizing investment and optimizing monitoring processes.
Key Features
Integrated UV-DOAS, NDIR, and ECD technologies in one system
High-precision, long-life UV-DOAS H2S sensor
Simultaneous monitoring of CH4, CO2, H2S, and O2 for process optimization
Modular sensor design for easy maintenance and calibration
Customizable gas regulation ranges to match site requirements
Stainless steel protection cabinet for corrosion resistance
Explosion-proof design (ExdIICT6) for hazardous areas
