II. Key Advantages (Anti-interference)
Resistant to H₂ (Hydrogen) Interference: Less likely to give false alarms in H₂-containing environments (mining, garages, battery compartments)
Resistant to C₂H₄ (Ethylene), NH₃ (Ammonia) Interference: Suitable for chemical industries, cold storages, agriculture, and new energy scenarios
Low Temperature Stability: Can operate normally at -40℃, suitable for northern regions / cold storages
Low Power Consumption, Long Lifespan: Electrochemical without heating, preferred for portable devices
III. Typical Applications
Portable Gas Detector
Four-in-One / Single CO Detector (mining, chemical industries, municipal services)
Firefighters, underground operations, confined space safety
Fixed Industrial Monitoring
CO Monitoring in Boiler Rooms, Garages, Parking Lots
CO Leakage Alarm in Chemical, Synthesis Ammonia, Coking Plants
New Energy / Battery Safety
CO Monitoring in Lithium Battery Warehouses / Workshops (evaporation of electrolyte)
Environmental Protection / IAQ
Indoor Air Quality, Smoke Emission, Combustion Efficiency Monitoring
Special Scenarios
Cold Storage (resistant to NH₃), Landfill (resistant to H₂/S)
Risk Control of Vehicle Exhaust, Ship Cabins, Tunnel Ventilation
