Gas Detection Capabilities

The device continuously monitors four critical gases:

1. Combustible gases (LEL): Detects flammable gases and vapors before explosive levels are reached.
2. Oxygen (O₂): Monitors oxygen concentration to identify oxygen-deficient or oxygen-enriched environments.
3. Carbon Monoxide (CO): Detects this odorless toxic gas produced by combustion.
4. Hydrogen Sulfide (H₂S): Monitors exposure to a highly toxic gas common in oil and gas industries.

These gases represent the most common workplace hazards in industrial and confined environments.
