Industrial gas detection

Industrial oxygen generally requires oxygen purity, and it also contains harmful gases such as carbon monoxide and methane that exceed the standard. It also has high levels of moisture, bacteria, and dust. Industrial oxygen is mainly used for welding, gas welding, gas cutting, etc. Industrial oxygen is a gas used in industrial production and product processing.

Oxygen classIndustrial gas detectionService Details

Applicable to sales bidding, factory re inspection, etc. of various oxygen industrial gases.

Common detection gases

• toxic gas：CO、H ₂ S、NH ₃、Cl₂、SO₂等。

• flammable gasMethane (CH ₄), propane (C ∝ H ₈), hydrogen (H ₂), etc.

• Oxygen (O ₂)Monitor hypoxic or oxygen rich environments (normal range 19.5%~23.5%).

• Volatile Organic Compounds (VOCs)Benzene, formaldehyde, etc.
