Rugged Oxygen O₂ Gas Detector for Industrial & Confined Space Safety
Engineered for durability and precision, the Rugged Oxygen (O₂) Gas Detector is a trusted solution for monitoring oxygen levels in industrial environments, confined spaces, tanks, and hazardous zones. This portable, heavy-duty device is built to withstand the toughest conditions, delivering real-time O₂ concentration readings to ensure a safe working atmosphere.
Featuring a high-sensitivity electrochemical sensor, the detector provides fast and reliable detection of both oxygen deficiency and enrichment, helping prevent respiratory hazards and combustion risks. The unit is enclosed in a shockproof, dustproof, and waterproof (IP66/IP67) casing, making it ideal for use in oil & gas, chemical, mining, utility, and construction sites.
With loud audio alerts, vibrant LED indicators, and strong vibration warnings, it ensures immediate attention to abnormal gas levels. The long-lasting rechargeable battery supports extended field operation, and the user-friendly interface simplifies operation even with gloves.
Key Features:
Real-time oxygen monitoring with high-accuracy sensor
Alerts for both low and high O₂ concentration levels
Triple alarm system: sound, light, and vibration
Rugged IP54-rated enclosure for harsh environments
Large LCD screen with backlight for clear readings
Rechargeable battery for continuous field use
Optional data logging and wireless communication
This rugged O₂ gas detector is an essential tool for confined space entry, industrial safety audits, and emergency response teams, offering dependable protection where it’s needed most.
