CPVAN Wireless 3-in-1 Carbon Monoxide Detector with Temperature & Humidity, Carbon Monoxide Alarms for Home Safety, CO Alarm with 10 Years Sensor Life, EN 50291, Replaceable Batteries. 1 Pack

【Safety Certification】 Compliance with EN 50291 standard and TÜV approval.
【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, 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.
【AA Batteries Included】 Equipped with batteries, there is no need to buy additional batteries, simply install batteries, test carbon monoxide detector and then mount it on the desired wall. If you want to use the co detector directly without mounting it, you can place it directly on the table. So easy!
【10 Years Sensor Life】 This carbon monoxide monitor is built electrochemical sensor to deliver high consistency and reliability for double detection and protection.
【Keeping Your Safety】 Place co alarm near the boiler, gas fire and room to rule out any carbon monoxide leaks. The display will tell you not only if carbon monoxide is leaking but at what rate. Every home with wood, coal, gas or oil burning fires should have one.
【Wider Detection Range】 CO range: 0 to 999 PPM; Humidity range: 1% to 99%RH (±3%RH); Temperature range: -9℃ to 99℃ (±1). The detector will cycle the alarm when the carbon monoxide concentration exceeds 50 ppm.
【Portable Carbon Monoxide Detector】 Can be wall mounted or free standing – ideal for taking on holiday or when travelling.
