Portable Carbon Monoxide Detectors for Home, Hotel, and Travel

【Plug and Play 3-in-1 Design】 The Gray Rhino carbon monoxide detector is a combined CO detector, room thermometer, and humidity meter, displaying and monitoring CO concentration, temperature, and humidity in real-time. It works with any standard 110-220V outlet, making it ideal for indoor use in homes, kitchens, living rooms, bedrooms, bathrooms, garages, and hotels.

【UL Test and Electrochemical Sensor】 All Gray Rhino carbon monoxide alarms are UL standard tested, with safety as the top priority. This plug-in CO detector utilizes an advanced electrochemical sensor that immediately produces electricity when exposed to carbon monoxide, resulting in faster response, higher accuracy, and greater resistance to interference from other gases compared to traditional sensors.

【2.1" HD Multi-functional CO Alarm】 The Gray Rhino travel carbon monoxide detector features a 2.1" HD IPS display and a highly accurate CO sensor that refreshes every 2 seconds to quickly detect surrounding CO levels ranging from 0-999PPM, with an accuracy of ±5PPM. It also functions as an indoor thermometer (14°F ~ 122°F, ±5%) and hygrometer (0 ~ 95%RH, ±5% RH), making it a versatile and convenient companion for travel and hotel stays.

【Easy to Use】 1. Plug the CO detector into a power outlet, and it will turn on. 2. Press "O" to test the alarm; if it beeps 3 times and the green indicator light flashes 3 times, the device is working properly. 3. Hold "O" to switch between °F and °C. 4. Press "H" to adjust the screen brightness among 3 modes. 5. Press "D" to turn the alarm on/off. The alarm will sound when CO levels exceed 50PPM, and can be silenced by pressing "D". However, when levels reach 200PPM or above, the alarm will sound automatically and cannot be manually turned off.

【Shopping Confidence】 Gray Rhino has designed this portable, plug-in CO detector with a focus on versatility, high sensitivity, and ease of use. The modern, compact, and pocket-sized design makes it suitable for a wide range of household applications.
