Rugged 4-in-1 Gas Detector for Confined Space & Industrial Safety
Stay safe in high-risk environments with the Rugged 4-in-1 Gas Detector, expertly engineered for confined space entry and industrial gas hazard detection. This durable, portable device continuously monitors four critical gases—Combustible Gases (LEL), Oxygen (O₂), Hydrogen Sulfide (H₂S), and Carbon Monoxide (CO)—to help prevent accidents, protect workers, and ensure compliance with safety regulations.
Built to perform in the most demanding conditions, it features a shock-resistant, water- and dust-proof design, backed by real-time readings, loud audible/visual/vibration alarms, and long battery life for uninterrupted field use.
Key Features:
4-in-1 Gas Detection: Simultaneously monitors LEL, O₂, H₂S, and CO—the four most common gas hazards in industrial and confined space environments.
Industrial-Grade Ruggedness: Designed to withstand drops, impacts, extreme temperatures, moisture, and dust. IP65/IP67-rated for use in harsh environments.
Confined Space Ready: Compact and lightweight with belt clip and lanyard support, making it easy to carry into manholes, tanks, tunnels, or silos.
Triple Alarm System: Built-in audible alarm (≥ 90 dB), bright LED strobe, and strong vibration instantly alert users to dangerous gas levels.
Real-Time Monitoring: High-contrast backlit LCD displays gas concentrations, battery status, and alarm conditions clearly—ideal for dark or enclosed spaces.
Long-Lasting Battery: Rechargeable lithium-ion battery supports up to 15–18 hours of continuous use, perfect for full-shift protection.
Calibration & Data Logging: Easy sensor calibration and optional data logging to help ensure safety compliance and accurate reporting.
