Product Description
On-line Coal Gas Analyzer KGD-MQ-521
The On-line Coal Gas Analyzer KGD-MQ-521 is used for online measurement of gas volume concentration. This advanced analyzer adopts non-dispersive infrared (NDIR) gas analysis technology with independent intellectual property rights, long-life electrochemical sensing technology, and MEMS-based thermal conductivity technology.
Product Features
- Simultaneous measurement: Measures gas components and calorific values simultaneously, including CO, CO₂, CH₄, H₂, O₂, and CₙHₘ, automatically calculating and displaying calorific values
- High measurement accuracy: No cross-interference among multi-component gases; CₙHₘ has no interference on CH₄ measurement, and CO, CO₂, and CH₄ have no interference on H₂ measurement
- Automated operation: Equipped with professional pre-treatment solution, digital and analog output functions, enabling real-time online monitoring without manual operation
- Stable performance: Constant-temperature sensor design eliminates ambient temperature influence; corrosion-resistant materials ensure long service life
