Product Overview
The Biogas Analyzer (Online Type) is a high-precision online monitoring device based on non-dispersive infrared gas analysis and long-life electrochemical sensor technology. This instrument can continuously measure the volume concentrations of CH₄, CO₂, H₂S, O₂, and other gases in biogas, offering precise multi-component measurement capabilities. It is widely applicable in biogas production, wastewater treatment, and landfill gas monitoring. The compact and reliable design ensures continuous monitoring, providing strong support for optimizing biogas process flows and ensuring safety management.
Key Features
- High Measurement Precision: Simultaneously measures the volume concentrations of CH₄, CO₂, H₂S, O₂, and other gases with no cross-interference between components, ensuring accurate data.
- Stable Operational Performance: Dual-channel sensor design with self-diagnostic functionality, enabling real-time monitoring of sensor status to ensure stable and reliable operation.
- Low Operating Costs: Compared to traditional methods such as the Orsat and gas chromatography techniques, this analyzer does not require frequent disassembly or chemical reagents, resulting in low operational and maintenance costs.
Applications
- Biogas Production: Real-time monitoring of biogas composition to ensure stable production and optimize gas quality.
- Wastewater Treatment: Monitoring of gas components in wastewater treatment processes to improve resource utilization efficiency.
- Landfill Gas Monitoring: Used in landfill sites to monitor biogas, preventing gas leakage and ensuring environmental safety.
- Agricultural Livestock: Monitoring biogas composition in livestock farms to develop effective ventilation and gas management solutions.
