Rechargeable 4-Gas Monitor for Industrial Safety Compliance
Ensure complete safety and compliance in hazardous work
environments with the Rechargeable 4-Gas Monitor, designed to
continuously detect and display levels of Combustible Gases (LEL),
Oxygen (O₂), Carbon Monoxide (CO), and Hydrogen Sulfide (H₂S).
Built for demanding industrial conditions, this compact and
portable gas detector offers reliable multi-gas protection, long
battery life, and easy operation—making it an essential tool for
professionals working in confined spaces, oil & gas facilities,
chemical plants, and more.
With advanced sensors, real-time display, and a powerful
rechargeable battery, this monitor delivers consistent performance
shift after shift, helping you meet industrial safety standards and
regulations.
Key Features:
4-Gas Detection in One Device: Simultaneously monitors LEL, O₂, CO,
and H₂S, offering comprehensive protection against common
atmospheric hazards.
Rechargeable Lithium-Ion Battery: Long-lasting power supports 12–18
hours of continuous operation on a single charge—ideal for daily
field use.
Real-Time Monitoring: Clear backlit LCD display provides instant
gas concentration readouts, battery status, and alarm indicators,
even in dark or confined areas.
Triple Safety Alarm: Loud audible alarm (≥ 90 dB), bright flashing
LED, and strong vibration alert you to dangerous gas levels
immediately.
Rugged Industrial Build: resistant to water, dust, and impact,
ensuring durability in challenging environments.
Easy Calibration & Operation: Simple interface and one-button
calibration streamline maintenance and training.
