氧气 Detection

⚠️ Hazards & Toxic Symptoms

Oxygen is a colorless and odorless gas, constituting 20.9% of the air normally. When the oxygen content falls below 19.5%, it is considered hypoxic. When it drops below 16%, headaches and decreased judgment occur. When it is below 6%, death can occur within minutes. Oxygen enrichment (> 23.5%) significantly increases the risk of combustion.

🏭 Typical Application Scenarios

• Mandatory inspection before working in a confined space
• Hospital oxygen pipeline
• Steel-making oxygen blowing
• Chemical reactor
• Semiconductor (O₃ oxidation)
