Détecteur portable de monoxyde de carbone CO 3 en 1 avec mesure de température et d’humidité, alarme numérique compacte pour voyage, camping, camping-car, maison et intérieur

【Multifunctional CO Meter】This is a 3-in-1 portable device combining carbon monoxide, temperature and humidity. It can not only measure CO concentration, but also air temperature and humidity. Measured values are updated every two seconds, which is much more frequent than traditional CO detectors and allows you to know the CO concentration almost in real time.

【Compact and portable】This mini CO detector is very compact and portable, and can also be used as a thermometer or hygrometer. It is perfect for traveling or camping in tents, cars, campers, houses equipped with a stove or factories equipped with an oven, where carbon monoxide poisoning can occur.

【Electrochemical gas sensor】This mini CO detector uses the principle of electrochemical reaction to quickly and accurately measure the concentration of CO. Built-in electrochemical carbon monoxide sensor features high accuracy measurement, good anti-interference ability and long service life. It is certified in accordance with the European standard EN-50291 for carbon monoxide detectors and offers high reliability.

【LCD screen and audible alarm】Measured values are displayed in real time on a 1.9-inch high-resolution color screen. Depending on the CO concentration, the detector also displays a colored alarm icon on the screen or emits a audible alarm. 51-100 ppm: alarm sounds 3 times every 3 minutes; 101-200 ppm: alarm sounds 5 times every 3 minutes; 201-1000 ppm: alarm sounds continuously (D6_orange)/alarm sounds 10 times per minute (D6_gray).

【Built-in 1000 mAh lithium battery】The built-in lithium battery can be fully recharged in about 4 hours and last up to 50 hours. This CO detector can also operate while it is charging and provide readings precise measurements. So you can always leave it connected to a USB power adapter to monitor the CO concentration continuously when necessary.

WARNING: This is a carbon monoxide (CO) detector and not a carbon dioxide (CO2) detector. When you turn on this detector in a normal living environment with clean air, it is normal for carbon monoxide reading or 0, because there is no carbon monoxide in clean air.

CAUTION: To check if the CO detector you received is working properly, you can bring it close to the smoke from burning materials such as paper or cigarettes, then wait 5 to 10 seconds. Due to combustion incomplete, the smoke generally contains carbon monoxide. If the CO detector is functioning properly, the screen reading will change and the CO detector will sound an audible alarm.
