Plug-in Type Carbon Monoxide Alarm CO Detector Monitor with LED Digital Display Voice Alert for Home Kitchen Independent carbon monoxide gas alarm controlled by microprocessor, stable operation sensitive response, small volume, simple installation and so on. It is used in places where carbon monoxide gas can leak, avoid dangerous accidents and ensure personal and property safety. Features: 1. High-precision & Sensitivity Sensor: Our CO gas detector use high reliability electrochemical sensor, excellent repeatability and stability, sensitive response, rapid alarm. 2. Easy to Install: The detector adapts excellent industrial design. Just plug in, and ready for monitoring potential gas leak risky after warm up process. 3. LED Digital Display & Voice Warning: When a carbon monoxide gas leak occurs, it can quickly identify the gas and emit an alarm of 85 decibels. The LED displays the carbon monoxide concentration value. It can avoid dangerous accidents and ensure personal and property safety. 4. Fault Detection: The carbon monoxide alarm has fault detection design. Press the "SELF-TEST" button, the alarm will give an alarm sound. At the same time, red and yellow indicator light, LED display "8888". 5. Low-power Design: The CO detector is suitable for 24 hours gas leak monitoring. With low power consumption design, it can save power and ensure life safety for a long time. Note: 1. Carbon monoxide detector does not work on liquid gas. Please do not use lighter gas, pipeline, gas, liquefied gas irrigation, natural gas test, this will damage the sensor. 2. Simple test method is to press the test button, such as the alarm sound, proved to be intact, can also get the honeycomb coal stove smoke outside, the detector chamber into carbon monoxide, the detector will alarm. Don't bake with fire. 3. Carbon monoxide gas is light. It is recommended to install on the ceiling, wall mounted within 30 cm from the ceiling. 4. A carbon monoxide detector can only manage one room, preferably in the bedroom, the carbon monoxide gas is light, the gas will follow the wall. The gap entered the room. 5. Use the test button regularly, clean the edge of the detector regularly and keep the environment ventilated. 6. Due to manual measurement, the size may be slightly different. Thank you for your understanding. 7. Due to different light conditions and different monitors, item color displayed in photos may be showing slightly different from real object.
