Pluggable Co Detector for Travel, Pluggable Co Detector for Travel with HD Screen and 85 dB Alarm Voice, 3-in-1 CO Detector (CO, T with Gift Box as last pictureA comprehensive CO detector plug-in design for home and travelCarbon monoxide is harmful. When the carbon monoxide content in the air exceeds the limit, it harms the human body and endangers life safety. This carbon monoxide detector plug-in has passed EN50291 certification and its quality is guaranteed. This plug-in carbon monoxide detector is compatible with 220V to 230V AC outlets. Fits all EU standard AC outlets in bedrooms, RVs, kitchens, living rooms, basements, hotel rooms and more.Advanced electrochemical sensor: When exposed to carbon monoxide, it immediately generates an electric current, which means it reacts faster and more accurately than conventional co-detectors and is less susceptible to influence by other gases. Please note that it is normal for the product to display a value of 000 PPM if there is no carbon monoxide gas in the air.2.1 inch high-definition display: On the 2.1 inch high-definition display, not only the value of the carbon monoxide concentration can be displayed intuitively, but also the temperature and humidity conditions that are important daily are clearly visible. Say goodbye to conventional carbon monoxide detectors that are a real eye-catcher with small screens.Intimate brightness design: If you feel that it is very energy-intensive to leave the HD screen on, you can press the "H" button to adjust the brightness state. When you turn off the screen brightness, the product continues to monitor and the indicator light reminds you every 5 seconds that the product is monitored normally. When the carbon monoxide concentration in the environment exceeds 50 ppm, the display screen of the carbon monoxide detector turns on quickly and sounds an alarm tone with more than 85 dB decibels to remember.High-precision comprehensive detector: The product is equipped with a precision CO sensor, which is updated every 2 seconds and can quickly detect the surrounding CO value. The detection range is 0-999 PPM and the accuracy is 5 PPM. It can also be used as an indoor thermometer with a temperature range of -10C to 50C and an accuracy of 3%; it can also be used as a hygrometer with a humidity range of 0 ~ 95% RH and an accuracy of 5% RH.Must-haves for household and safety utensils for travel: When you are travelling, staying in a hotel, travelling in a motorhome or camping outdoors, this portable plug-and-play carbon monoxide detector can make your trip safer. If you are worried that conventional carbon monoxide detectors require regular battery changes and the small screen can barely detect the carbon monoxide concentration, you can clearly see the carbon monoxide concentration, temperature and humidity with this three-in-one detector.
