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.
