Three-in-one multi-functional This three-in-one portable carbon monoxide detector offers more integrated functions and continuous upgrades. It adopts a newly upgraded 43-hole design, which can not only accurately detect the concentration of carbon monoxide in the air (0-500 ppm), but also measure humidity (0 to 90% relative humidity) and temperature (32°F to 122°F). The three-stage display system of the CO detector makes safety visible, making it the perfect tool for monitoring air safety in any environment

High-precision real-time detection: This carbon monoxide detector adopts the most advanced and sensitive gas sensor to quickly detect and respond to the level of carbon monoxide in the air. With a refresh time of 1 second, it ensures the accurate detection and real-time update of environmental air data. These data are clearly displayed on a 1.5-inch high-definition screen, keeping you and your family away from invisible dangers

Intuitive and clear alarm: CO detector value: 0-49ppm, green (safe); 50-99 PPM, yellow (low-frequency warning), accompanied by a slower "beeping" alarm; 100-500 PPM, red (high-frequency alarm = danger), accompanied by a rapid "tick-tock" alarm sound; After turning on the device, you can customize the alarm value by pressing the button twice more (first press the short button twice, then press it long once to select the device, and press it short once again to set the value).

Ultra-long standby time: The carbon monoxide detector battery is equipped with a 1500mAh battery and Type-C fast charging technology.
