- 3-in-1 Air Safety Companion: This sleek portable detector combines real-time tracking of CO levels (0-500 PPM), humidity (0-90% RH), and temperature (32°F–122°F). With an upgraded 43-hole structure and HD display, it delivers precise air quality monitoring for safety in any environment.
- Smart Home Safety Companion: Equipped with an upgraded electrochemical sensor for precise and long-lasting CO detection, this 3-in-1 detector monitors CO levels (0-1000 PPM), humidity (0-95% RH), and temperature (-4°F–140°F) in real time. With a 1-second refresh rate and a 1.5″ HD display, it ensures instant, clear updates. The device triggers alerts in 3 minutes at 50-100 PPM, 5 minutes at 101-200 PPM, and continuous alarms above 200 PPM, keeping your home safe from invisible dangers.
- Long Battery Life, Safe to Go: Equipped with a 1000mAh Li-ion battery, this handheld travel CO monitor boasts an impressive standby time of up to 360 hours (15 days). When in power-saving mode, the screen auto-sleeps after 30 seconds, and the device switches to low power mode while the CO monitoring continues uninterrupted. The Type-C charging feature adds convenience, eliminating the need for frequent battery changes. It's the perfect companion for home use, travel, or camping adventures.
- Portable Design:Our 3-in-1 CO detector is a versatile companion for both indoor and outdoor adventures. It features a lanyard, kickstand, and screw buckle hole for easy hanging, wall mounting, or stable placement. The lightweight design ensures effortless travel, making it ideal for camping tents, boats, RVs, kitchens, and more.
- How to Safely Test Your CO Detector: To test your carbon monoxide detector, place it near a source of thick smoke, such as a lit cigarette or burning paper. The CO levels will display on the screen. Avoid using car exhaust or testing in airy places, as low CO concentrations won't activate the sensor. This method ensures accurate testing and safe operation.
