The Honeywell FGM-3300/NO2 is a fixed gas detector designed for continuous monitoring of nitrogen dioxide (NO₂) in industrial and confined spaces. Its electrochemical sensor provides ±2% FS accuracy with a 0–20 ppm range, while 4–20 mA/Modbus outputs enable seamless integration with control systems. The IP66-rated housing and ATEX/IECEx certifications make it suitable for harsh or hazardous environments. Ideal for ventilation control in parking garages, tunnels, and chemical plants.
