The Metravi GD-09-4M Multi-Gas Detector is a versatile and reliable safety tool designed to detect multiple gases, including Explosive Gas (EX), Oxygen (O2), Carbon Monoxide (CO), and Hydrogen Sulphide (H2S), simultaneously and continuously. With a rugged, explosion-proof design rated IP65, the GD-09-4M is ideal for environments where toxic gases or combustible gas leaks are a risk, such as underground channels, mining sites, warehouses, and more. It also provides added safety in residential or commercial spaces, offering protection to lives and valuable equipment. Equipped with a large LCD display, this multi-gas detector provides clear, real-time readings and features visual, audio, and vibration alarms to ensure immediate alert in case of gas level fluctuations.

Key Features:

• Four-Gas Detection: Simultaneously detects Explosive Gas (EX), Hydrogen Sulphide (H2S), Carbon Monoxide (CO), and Oxygen (O2), ensuring comprehensive safety coverage.
• High-Sensitivity Sensor: Equipped with a high-sensitivity sensor that provides accurate and repeatable readings using natural diffusion sampling.
• User-Friendly Interface: Large LCD screen for clear and intuitive readings, displaying real-time gas levels and system status.
• Robust Construction: Built with high-strength engineering plastic, anti-slip rubber, and IP65-rated for water and dust resistance, ensuring durability in harsh environments.
• Triple Alarm System: Alerts users with LED, audio, and vibration alarms when gas levels are out of safe range.
• Low Battery and Sensor Fault Indications: Provides low battery and sensor fault warnings for continuous, reliable operation.
• Rechargeable Battery: Powered by a 3.7V, 2000 mAh Li-ion battery with 8 hours of continuous runtime on a single charge.
