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
