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. | Product Name | 4 gas detector | | Model | X-4 | | EX Detection range/Resolution | (0~100)%LEL, 1%LEL | | H2S Detection range/Resolution | (0~100)PPM, 1PPM | | CO Detection range/Resolution | (0~1000)PPM, 1PPM | | O2 Detection range/Resolution | (0~30)%VOL, 0.1%VOL | | EX Low alarm/High alarm | 20%LEL, 50%LE | | H2S Low alarm/High alarm | 10PPM, 20PPM | | CO Low alarm/High alarm | 50PPM, 200PPM | | O2 Low alarm/High alarm | 19.5%VOL, 23.5%VOL | | Error | ±5% FS (combustible),±10% FS (carbon monoxide),±10% FS (hydrogen
