2-50 KPa Inlet Gas Pressure KGD MQ 527 Online Biogas Monitoring System With RS232/485 Digital Signal

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.
