Product Description

On-Line Coal Gas Analyzer KGD-MQ-521
For On-Line Measurement of Gas Volume Concentration
The On-Line Coal Gas Analyzer KGD-MQ-521 is designed for continuous measurement of gas volume concentration in industrial applications.
On-Line Coal Gas Analyzer KGD-MQ-521 device showing professional industrial design
Product Introduction
The KGD-MQ-521 analyzer utilizes advanced non-dispersive infrared (NDIR) gas analysis technology combined with long-life electrochemical sensing and MEMS-based thermal conductivity technology. This system provides simultaneous measurement of coal gas and biogas calorific values along with volume concentrations of CO, CO₂, CH₄, H₂, O₂, and CₙHₘ gases.
Key Features
  • Comprehensive gas analysis: Measures volume concentrations of multiple gas components (CO, CO₂, CH₄, H₂, O₂, CₙHₘ) while automatically calculating and displaying calorific values for coal gas and natural gas.
  • High precision measurement: Eliminates cross-interference between measured gases, ensuring accurate results unaffected by gas sampling flow changes.
  • Automated operation: Features professional pre-treatment solution with digital/analog outputs, enabling real-time monitoring with minimal maintenance.
  • Durable construction: Constant-temperature sensor design with corrosion-resistant materials (stainless steel, PTFE) ensures long-term reliability.
