Carbon monoxide detectors, portable CO alarm detection device with LCD digital display for home and travel, UL listed carbon monoxide alarm with electronic sensor

【Fast and Accurate Detection】The carbon monoxide detector is an advanced integrated electrochemical CO sensor that provides high-precision alarms for fast and accurate detection of carbon monoxide levels. When the carbon monoxide concentration exceeds the specified values, an alarm of over 85 decibels will be emitted. To ensure complete protection, be sure to place one on each floor of your house and in each room. 【Wide Adaptability】The carbon monoxide detector is suitable for all places where carbon monoxide can be produced, such as your kitchen, bedroom, bathroom, warehouse, hotel, car, parking lot or barbecue! The portable carbon monoxide detector is powered by 2 AAA 1.5V batteries (not included), which is easy to use, with a single test/reset button. 【LCD Digital Display and LED Indicators】The carbon monoxide detector features a digital LCD display that shows real-time CO levels, allowing you to see any significant changes in CO levels, and can display the battery life, prompting you to replace the batteries. The intuitive LED indicator clearly informs you of the operating status of the CO alarm detector: the green LED indicates normal operation, the red LED indicates alarm status, and the yellow LED indicates a fault. 【Portable and Easy to Install】The carbon monoxide detector is easy to install without rewiring. It can be mounted on any wall or ceiling, as well as in a car. This CO detector includes mounting brackets, screws and wall plugs, and comes with 3M adhesive. It is not only an ideal carbon monoxide measuring device for home use, but also a must-have for the car or travel. 【Quality Assurance】All CO alarms are thoroughly tested and meet UL standards. If you have any questions about our CO detectors, please feel free to contact us. (Note: When testing the detector, please do not blow the hole directly with gas.) Specifications: Item: Carbon Monoxide Detectors Battery Power Supply: 2*1.5VA AA batteries (not included) Sensor: Electrochemical Operating Temperature: 0-70°C Operating Humidity: 10%-95% relative humidity Carbon monoxide gas detection concentration: 0~999 PPM Alarm indication: LCD screen, audible and visual alerts Alarm standard: When the carbon monoxide concentration is detected as exceeding 30 ppm, the alarm screen will illuminate and the real-time carbon monoxide concentration in the air will be displayed. When the concentration reaches 100 ppm, the detector will immediately emit an audible alarm of more than 85 dB and flash a red LED for the alarm!
