四合一 Detection
Formula 复合（O₂+CO+H₂S+LEL） · 多合一气体监测
Hazards & Toxic Symptoms
The 'four-in-one' configuration is a standard feature of portable gas detectors: oxygen (O₂), carbon monoxide (CO), hydrogen sulfide (H₂S), and combustible gas (LEL). It covers over 90% of the risks associated with confined space operations.
Typical Application Scenarios
- Work in confined spaces (underground/inside tanks)
- Municipal pipeline network inspection
- Chemical / Petroleum and Petrochemical
- Fire emergency response
- Construction site
Detection Principle / Recommended Sensors
Electrochemical (O₂/CO/H₂S) + Catalytic Combustion (LEL)
