Product Overview
The Portable Biogas Analyzer is a compact and lightweight gas detection device designed for on-site and laboratory biogas analysis. It combines Non-Dispersive Infrared (NDIR) technology with long-life electrochemical sensors to simultaneously measure the volume concentrations of CH₄, CO₂, H₂S, O₂, and other gases in biogas. The instrument offers high measurement accuracy, rapid response, and user-friendly operation, providing an efficient and portable solution for biogas monitoring and analysis.
Working Principle
- NDIR Technology: Measures concentrations of combustible gases such as CH₄ and CO₂ with high precision.
- Electrochemical Sensors: Detect H₂S, O₂, and other toxic or reactive gases.
- Multi-Component Analysis Algorithm: Processes sensor data to calculate and display accurate concentrations for all measured gases, avoiding cross-interference.
Key Features
- Portable Design: Lightweight and compact, easy to carry for industrial field use, and compatible with laboratory gas bag sampling.
- High Measurement Accuracy: Simultaneously measures multiple gases (CH₄, CO₂, H₂S, O₂) with minimal cross-interference.
- Smart Power Management: Soft-start switch and intelligent battery management ensure stable operation even at low battery levels.
- Easy Data Management: Equipped with multiple interfaces to transmit real-time measurement data to central control systems for monitoring and analysis.
- Rapid Response: Provides immediate measurement results, ideal for dynamic industrial or laboratory environments.
Applications
- Biogas Production & Power Generation: Monitors biogas composition in real-time, optimizing gas quality and production efficiency.
- Wastewater Treatment Plants: Tracks biogas generated during wastewater processing to enhance energy utilization.
- Environmental & Agricultural Monitoring: Monitors biogas in landfills, livestock facilities, and other agricultural sites, ensuring safe and sustainable operations.
