Good afternoon! Great question - NDIR technology has significant advantages for industrial applications! Let me share my experience with NDIR Gas Sensors https://mgs-technology.com/products/gassensors/ from MGS Technology. We switched from electrochemical sensors to NDIR two years ago and haven't looked back. The key advantage is long-term stability - electrochemical sensors drift over time and need frequent calibration and replacement, while NDIR sensors maintain accuracy for years. They're immune to sensor poisoning, which was a major issue with our previous sensors in chemical environments. The optical principle of operation provides inherent reliability - no consumable components to replace regularly. MGS Technology's NDIR sensors use LED-based systems with optimized spectrum, which dramatically reduces power consumption compared to traditional IR sources. Their sensors have solid-state transmitter and receiver, making them highly resistant to vibration - crucial for industrial environments. They also have integrated temperature sensors for automatic compensation, ensuring stable readings across different conditions. For portable applications, their MIPEX-04 sensors have incredibly low power consumption (~0.1 mW average), enabling up to 24 months of autonomous operation on batteries. Definitely recommend NDIR for any serious industrial gas detection application!
