Advanced 4-Gas Monitoring Solution for Safety in Industrial Environments
Enhance safety protocols with the Advanced 4-Gas Monitoring Solution, built to meet the rigorous demands of industrial environments. This professional-grade device continuously monitors Oxygen (O₂), Carbon Monoxide (CO), Hydrogen Sulfide (H₂S), and Combustible Gases (LEL), providing real-time protection against life-threatening gas hazards in confined spaces, factories, refineries, and construction sites.
Equipped with precision sensors and advanced signal processing technology, the detector offers rapid, accurate readings with minimal false alarms. The user-friendly interface features a high-contrast color screen for easy data interpretation, even in low-light or high-glare settings.
Designed for both portability and durability, the monitor boasts an impact-resistant, dustproof, and water-resistant housing (IP-rated), making it ideal for tough working conditions. Integrated alarms—visual, audible, and vibration—alert workers instantly when gas levels exceed safety thresholds.
Key Features:
Monitors O₂, CO, H₂S, and LEL gases simultaneously
High-precision sensors with real-time data display
Audible, visual, and vibration alarms for quick hazard response
Rugged, ergonomic design with IP65/IP67 protection
Rechargeable battery for extended field use
Optional data logging, 1900 data at 0.1-10 configurable interval
Compatible with smart safety systems and industrial automation networks
The perfect tool for ensuring worker safety, regulatory compliance, and peace of mind in high-risk industrial operations.
