氢气 Detection
Formula H₂ · CAS 1333-74-0 · 极易燃 / 极宽爆炸范围
Hazards & Toxic Symptoms
Hydrogen is a colorless, odorless, and non-toxic gas, but it is highly flammable, with an explosion range of 4-75% (one of the widest gases). The ignition energy is extremely low (0.02 mJ). It is lighter than air and tends to accumulate at the top due to upward diffusion.
Typical Application Scenarios
- Hydrogen energy/fuel cell
- Petrochemical (Hydrofining)
- Semiconductor (CVD)
- Glass/Electronic Grade Gas
- Aerospace
Detection Principle / Recommended Sensors
Catalytic combustion (most common) / thermal conductivity (ultra-high concentration) / semiconductor-specific H₂
Common Range：0-100% LEL / 0-100% Vol
