5 in 1 Carbon Monoxide Detector, Smoke and Gas Detector, Black | HD Display, Temperature and Humidity Sensor, For Caravan, Home, Travel and Kitchen

• 5-in-1 Multi-Threat Detection System: The device works instantly when plugged into a household electrical socket (110V-240V) and continuously monitors carbon monoxide (CO), smoke, and flammable gases. Features a 2.7 inch HD digital display showing gas levels, temperature and humidity. Equipped with a dual sensor system, the device provides quick and accurate detection to protect your family from multiple threats
• High Performance with Long Service Life: The device uses the principle of electrochemical reaction and semiconductor resistance switching to quickly and accurately detect carbon monoxide, fumes and flammable gases. The sensor on this device has high performance and a service life of about 5 years
• Extremely Reliable and Accurate Sensors: These carbon monoxide and natural gas leakage detectors with high-precision sensors refresh every 2 seconds to provide the most accurate data. Features an intuitive, large color LCD screen that makes it easy to read CO, smoke, flammable gases, humidity and temperature levels. Laboratory tested and conforms to EN146044, EN50291 and EN50194 standards
• Sound and Light Alarm System: Smoke and carbon monoxide detectors have an integrated sound and light dual warning system. Plug and play carbon monoxide detector activates when smoke alarm triggers, carbon monoxide levels exceed 200ppm, or dangerous gas concentrations are detected, with a flashing symbol and loud sound to alert you to take action immediately
• Plug and Play with Portable Design: Portable carbon monoxide detector provides flexibility to adapt to any space by providing both plug and battery-powered options. Built-in 1000mA rechargeable battery allows smoke and carbon monoxide alarms to work for 24 hours during power failures. Small and compact design (1.46 x 1.8 x 1.02 inch) suitable for outdoor activities, camping tents, boats, stoves, stove heating, vehicles and other tight spaces
• Widely Used for Continuous Monitoring: Plug-in Smoke and Carbon Monoxide Detector can monitor the leak of natural gas and CO concentration in real time for 24 hours, maintaining the respiratory health of you and your family at all times. Easy to carry in backpack, bedroom, kitchen, stove, bathroom, apartment, garage, office, restaurant, hotel, RV, travel, and other locations
• Testing Instructions for Proper Operation: Incomplete combustion produces carbon monoxide and smoke. The device can be tested by placing it next to a cigarette or burning paper to produce thick smoke and CO. The concentration of gas and smoke will change and be displayed on the display. Do not test on car exhaust or in an airy place, as too low CO concentration cannot trigger the operation of the sensor
