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 features an advanced 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 value, an alarm of over 85 decibels will sound.For complete protection, be sure to place one on each floor of your home and in each room.【Wide Adaptability】The carbon monoxide detector is suitable for any location where carbon monoxide may be produced, such as your kitchen, bedroom, bathroom, warehouse, hotel, car, parking lot, or barbecue area!The portable carbon monoxide detector is powered by 2 AAA 1.5V batteries (not included), making it easy to use with a single test/reset button.【LCD Digital Display & 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 also display the battery life, prompting you to replace the batteries.The intuitive LED indicator clearly shows the operating status of the CO alarm detector: a green LED indicates normal operation, a red LED indicates alarm status, and a yellow LED indicates a fault.【Portable & 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 anchors, and comes with 3M adhesive.It's not only an ideal carbon monoxide measuring device for home use, but also a must-have for the car or for travel.【Quality Assurance】All CO alarms have been rigorously 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 gas directly into the hole.)Specifications:Item: Carbon Monoxide DetectorsBattery Power Supply: 2*1.5VA AA batteries (not included)Sensor: ElectrochemicalOperating Temperature: 0-70°COperating Humidity: 10%-95% relative humidityCarbon Monoxide Gas Detection Concentration: 0~999 PPMAlarm Indication: LCD screen, audible and visual alertsAlarm 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 a loud alarm of over 85 dB and flash a red LED light!Package includes:1 x Carbon Monoxide Alarm1 x User Manual2 x Screws2 x Backing Adhesive
