KGD-MQ-528 Integrated Biogas Analysis System with CH4 Measurement Range 0-100% and H2S Resolution 1ppm

KGD - MQ - 528 Integrated Biogas Analysis System

Product Introduction

The KGD - MQ - 528 Integrated Biogas Analysis System uses non - dispersive infrared gas analysis technology with independent intellectual property rights and long - life electrochemical sensing technology. It can continuously monitor the volume concentrations of gases such as CH4, CO2, H2S, and O2 in biogas components in real - time and online. The system can be optionally equipped with a pretreatment unit to achieve multi - channel sampling and water - removal functions, adapting to various biogas working conditions on - site.

Product Features

  • High Measurement Accuracy and Long Service Life
  • It can simultaneously measure the volume concentrations of gases such as CH4, CO2, H2S, and O2 in biogas components online, with no cross - interference among multi - component measured gases. The patented technology of the unique H2S sensor protection device extends the service life of the sensor.
  • Stable Working Performance
  • The sensor adopts a dual - channel design, which is highly stable. It has a self - diagnosis function and can check the sensor status online.
  • Convenient Data Management
  • Data can be transmitted to the superior centralized control system through multiple interfaces, providing real - time basis for remote monitoring and process adjustment.
  • High Degree of Automation
  • It is equipped with a fully automatic, maintenance - free pretreatment device, which can operate stably, accurately, continuously, and automatically online for a long time without the need for manual attendance, greatly reducing the labor cost of enterprises.
  • Simple Operation and No Consumables
  • Compared with gas analysis technologies such as Orsat and chromatography, the measurement process does not require disassembly and installation, nor does it consume chemical reagents. It is simple to operate and has no consumables.
