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.
