KGD - MQ - 527 Online Biogas Monitoring System
Product Introduction
The KGD - MQ - 527 Online Biogas Monitoring System is a new - generation biogas monitoring system. It accurately measures the concentration of H2S before and after biogas desulfurization based on Ultraviolet Differential Optical Absorption Spectroscopy (UV - DOAS) gas analysis technology, measures the concentrations of CH4 and CO2 using Non - Dispersive Infrared (NDIR) gas analysis technology, and measures the concentration of O2 by Electrochemical Detection (ECD) method. With a modular sensor design, it can realize continuous online monitoring of biogas components.
To ensure the efficiency of biogas desulfurization equipment, two sampling channels are used before and after the scrubber to monitor the H2S concentration in real - time, effectively preventing excessive H2S from damaging the downstream pipelines and other equipment. The KGD - MQ - 527 is suitable for various biogas working conditions on - site, providing an ideal solution for minimizing user investment and optimizing the biogas digester monitoring process.
Product Features
- Unique combination technology of UV - DOAS, NDIR, and ECD.
- Capable of measuring high and low range H2S before and after desulfurization.
- High - precision, long - life UV - DOAS H2S sensor.
- Continuously monitors CH4, CO2, H2S, and O2 to optimize process control.
- Modular sensor design for easy calibration and maintenance.
- Flexible gas regulation configuration, with ranges customizable according to on - site requirements.
- Stainless - steel protection cabinet to prevent the instrument from gas corrosion during long - term operation.
- Explosion - proof design, suitable for flammable and explosive hazardous areas.
