KoreaTech NDIR Gas Analysis System KRFG-3500 is an online gas monitoring system with a highly flexible configuration, capable of measuring CH₄, CₙHₘ, CO, CO₂, H₂, O₂, H₂S, calorific value, Wobbe index, and other gas parameters.
Feature & Specification
Gas Calorific Value Analyzer
- High-speed response and continuous measurement based on NDIR and other technologies.
- Real time calculation of calorific value and wobbe index.
- No carrier gas needed, replacement to gas chromatography, mass spectrometry.
- Modular sensor design ensures simple maintenance.
- EX-Proof design with CNEX certification.
- Optional air purging module can prolong electrochemical sensor lifetime.
- Thermostatic design for sensors to reduce temperature fluctuation influence.
- All parts contacting with sample gas are made of high corrosion resistant material.
- Auto diagnosis function to check sensor status quickly.
- Capable of measuring multiple sampling channels.
