Main Highlights

【Safety Certification】 Compliance with EN 50291 standard and TÜV approval. CPVAN has always provided customers with officially certified products to ensure safety. CO detector is equipped with high accuracy and reliable electrochemical sensor, continuously measure CO concentration in ambient air.
【10 Years Sensor Life】 This carbon monoxide monitor is built electrochemical sensor to deliver high consistency and reliability for double detection and protection. Equipped with replaceable batteries, you can just replace it when the power is low for easy handling. Test your carbon monoxide alarm regularly to ensure it is operational.
【3 in 1 Carbon Monoxide Detector】 Simultaneously detects Carbon Monoxide, Humidity and Temperature! 0 second real-time detection, CO concentration data refresh rate: 4 seconds. The CO alarm responds quickly, alerting you to a potential hazard with an 85 dB alarm as soon as it is detected.Temperature and humidity updated every minute, so you always know the air quality of your surroundings.
【Carbon Monoxide Alarm】 Continuous monitoring for CO. Digital display of CO levels from 25 ppm. Detector alarms from 50 ppm. The alarm time depends on the level of carbon monoxide concentration and the display screen of the carbon monoxide alarm accurately shows carbon monoxide concentration data. The carbon monoxide alarm will notify you immediately when the concentration reaches a certain level, minimizing false alarms.
【Sleek and Portable】 this small and unobtrusive carbon monoxide detector looks good in any room, meaning you never have to compromise style for safety. CO alarm use versatile free-standing design, making it easy to place on a tabletop or mount on a wall. Its portability also allows you to take it with you while traveling, ensuring your safety wherever you go.
