Industrial-Grade 4-Gas Detector for Confined Spaces and High-Risk
Areas Protect your team with the Industrial-Grade 4-Gas Detector,
specifically designed for confined spaces and high-risk industrial
environments. This rugged, portable detector simultaneously
monitors four critical gases—Oxygen (O₂), Carbon Monoxide (CO),
Hydrogen Sulfide (H₂S), and Combustible Gases (LEL)—ensuring
comprehensive safety in real time. Engineered with precision sensors and a durable, shock-resistant
housing, this device delivers fast, accurate readings in
challenging conditions such as tunnels, tanks, silos, wastewater
plants, and oil & gas facilities. The bright digital display
and intuitive interface make it easy to operate, even while wearing
protective gear. With high-decibel audible alarms, flashing LEDs, and vibration
alerts, the detector ensures that workers are immediately notified
of dangerous gas levels. The unit is IP-rated for water and dust
resistance, and includes a long-lasting rechargeable battery to
support extended field use. Key Features: Simultaneous detection of O₂, CO, H₂S, and LEL gases Real-time monitoring with high-accuracy sensors Triple alert system: audible, visual, and vibration Compact, lightweight, and intrinsically safe design Rechargeable battery with long operational runtime Data logging and optional wireless communication
(Bluetooth/WiFi/LoRa) Ideal for confined spaces, industrial plants, emergency response,
and hazmat teams Ensure safety and compliance with this essential gas detection
solution for high-risk work zones.
