Handheld Oxygen O2 Gas Detector 0 to 30% Vol for confined space
The Handheld Oxygen O₂ Gas Detector is a compact, portable, and highly accurate device designed for real-time monitoring of oxygen levels in a wide range of environments. Whether you're in industrial workspaces, confined spaces, laboratories, or emergency response situations, this rugged detector ensures reliable safety and fast response when it matters most.
Key Features:
Real-Time Oxygen Detection: Accurately measures oxygen (O₂) concentration levels in the air and provides real-time readings to help identify oxygen-deficient or oxygen-enriched environments.
High Accuracy & Fast Response: Built with a sensitive electrochemical O₂ sensor, this detector delivers precise readings with a fast response time, ensuring early detection and quick decision-making in critical situations.
Portable & Lightweight: Designed for one-handed operation, this handheld detector is lightweight, ergonomic, and easy to carry, making it ideal for on-the-go use in fieldwork and inspections.
Clear Digital Display: The bright, high-contrast LCD screen shows real-time O₂ levels, battery status, alarm indicators, and more—easy to read even in low-light conditions.
Rechargeable Battery: Equipped with a long-lasting lithium battery that supports up to 2 years.
