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.
