High Precision Gas Volume Concentration Measurement With KGD MQ 520 Portable Coal Gas Analyzer

The Portable Coal Gas Analyzer KGD-MQ-520 measures gas volume concentration using advanced non-dispersive infrared (NDIR) technology, electrochemical sensing, and MEMS-based thermal conductivity technology. This analyzer provides simultaneous measurement of coal gas and biogas calorific values along with volume concentrations of multiple gases.

• Comprehensive gas analysis: Measures CO, CO₂, CH₄, H₂, O₂, CₙHₘ concentrations and calculates calorific values, eliminating need for separate calorimeters
• High accuracy technology: NDIR, TCD, and ECD measurement principles ensure minimal cross-interference between gas components
• Portable design: Compact 9kg unit suitable for both field industrial measurements and laboratory analysis
• Smart power management: Intelligent battery system with soft-start power switch prevents low-power operation
• Data management: Automatic data storage with query/delete functions and multiple interface options for data transmission
• Low operational cost: No chemical reagents or complex installation required compared to traditional analysis methods
