Hazards & Toxic Symptoms
"Combustible gas" is a comprehensive indicator for LEL monitoring, encompassing all combustible volatiles such as methane, propane, hydrogen, and gasoline vapor. When the sensor reading reaches 25% of the LEL, an alarm should be triggered; when it reaches 50%, emergency evacuation is required.
Typical Application Scenarios
- All flammable gas usage/storage scenarios
- Chemical plant monitoring
- Gas station/gas terminal
- Laboratory
Detection Principle / Recommended Sensors
Catalytic combustion (most common) / Infrared (high concentration, oxygen-free)
Common Range：0-100% LEL
