4-in-1 Multi Gas Detector with CO H2S O2 LEL Monitoring & Triple Alarm

Stay aware of hazardous gas conditions before they become harder to manage. The SMART SENSOR ST8900 is a portable 4 in 1 gas detector that continuously monitors carbon monoxide, hydrogen sulfide, oxygen, and combustible gas (LEL) levels. Designed for industrial teams, technicians, inspectors, and confined-space work, it puts four critical readings on one clear backlit LCD. Sound, light, and vibration alerts provide multiple warning signals when concentrations reach preset alarm levels. Its compact handheld design also supports connection to a sampling pump for closed-space testing.

Key Features

• Simultaneously monitors CO, H2S, O2, and LEL for convenient 4-gas coverage.
• Carbon monoxide detector functionality helps identify CO concentrations alongside other workplace gas hazards.
• Adjustable alarm concentration and automatic shutdown settings provide greater control.
• Clear backlit LCD makes readings easy to check, while audible, visual, and vibration alarms help warnings get noticed.
