Advanced Multi-Gas Monitor – Combustible, Oxygen, Hydrogen Sulfide & CO
Protect your workforce and workplace with the Advanced Multi-Gas Monitor, designed to deliver fast, accurate, and reliable detection of the most common industrial gas hazards: Combustible Gases (LEL), Oxygen (O₂), Hydrogen Sulfide (H₂S), and Carbon Monoxide (CO). Engineered for professional use in high-risk environments, this compact and durable device provides continuous real-time monitoring, clear visual feedback, and instant alarms to alert users of any dangerous gas presence.
Ideal for confined space entry, oil & gas operations, chemical plants, and industrial safety applications, this monitor is a must-have for any team working in potentially hazardous conditions.
Key Features:
Simultaneous 4-Gas Detection: Continuously tracks and displays concentrations of LEL, O₂, H₂S, and CO on a single easy-to-read interface.
High Sensitivity Sensors: Advanced electrochemical and catalytic sensors offer fast response times and accurate readings, even in rapidly changing environments.
Real-Time Data Display: Large backlit LCD shows current gas levels, battery status, and alarm conditions at a glance.
Triple Alarm System: Built-in visual (LED), audible (≥ 90 dB), and vibration alerts ensure users are notified immediately when thresholds are exceeded.
Rugged & Weather-Resistant: Built tough for harsh environments with a shock-resistant, water- and dust-proof design.
