天然气 Detection
Formula CH₄ 主成分（>85%） · CAS 8006-14-2 · 可燃 / 窒息（密闭空间）
Hazards & Toxic Symptoms
Natural gas primarily consists of methane (85-95%), which emits a rotten egg odor after being odorized with odorant (THT/ethyl mercaptan). Its lower explosion limit is 5%. It is lighter than air and tends to disperse upwards.
Typical Application Scenarios
- Urban gas pipeline network
- LNG receiving terminal
- Natural gas power plant
- Gas station
- Industrial fuel
Detection Principle / Recommended Sensors
Catalytic combustion (preferred) / Infrared / Laser remote sensing (pipeline inspection)
Common Range：0-100% LEL
