Feature: 1. Ultra Sensitive Detection: Natural gas detector with digital display has the ability to detect even trace amounts of explosive gases, providing early warning alerts to ensure user safety. 2. Versatile Applications: This detector is suitable for various settings including kitchens, households, and RVs. It effectively detects the presence of combustible gases, preventing fires and explosion accidents. 3. Plug in Design: The detector features a convenient plug in design. Users simply insert the detector into a suitable location, and it will immediately start detecting combustible gases without the need for complex installation steps. 4. Efficient Alarm System: Once the detector detects combustible gases exceeding the safety threshold, it will promptly emit a loud alarm, alerting users to take the necessary precautions for timely evacuation and handling. 5. Safety and Reliability: Gas detector utilizes durable materials and advanced sensor technology, ensuring stability and reliability for long term operation, effectively safeguarding user safety. Specification: Item Type: Gas DetectorMaterial: ABS Gas Detected: Liquefied Gas, Natural Gas, Artificial Coal GasVoltage: AC100V-AC240V Alarm Concentration: Approx. 3%LEL - 20%LEL Alarm Loudness: ≥85dB (at a distance of 3 meters / 9.8ft from the product) Description: This standalone combustible gas alarm uses advanced gas sensitive technology and a cost effective microprocessor as the control core. It is a small gas safety product suitable for home use, designed to continuously detect indoor gas leakage concentration. When the leakage concentration reaches the set value, the detector will sound and flash to alert users. It automatically returns to normal working status when the indoor gas concentration is lower than the alarm set value, effectively preventing accidents such as poisoning, explosions, and fires caused by gas leaks, ensuring personal safety and property prevention.
