About This

• 【High-Precision 3-in-1 CO Detector】This 3-in-1 portable carbon monoxide detector tracks CO levels, temperature, and humidity in real time. Equipped with a high-precision sensor with a 10-year lifespan, it measures CO from 0–500 PPM, temperature from 14–122℉ (-10–50℃), and humidity from 0–95% RH. Accurate and instant readings keep you informed about your environment’s air quality at all times
• 【3 Light Indications & Custom Alarm Values】The carbon monoxide alarm features three light indicators based on CO concentration levels in the air: 0–49 PPM (Green light flashing = Safe), 50–99 PPM (Yellow light flashing = Warning), 100–500 PPM (Red light flashing = Danger). By default, the alarm activates at 50 PPM. You can double-click the "function key" to set a custom CO threshold. When the alarm sounds, press the "function key" to pause it for 15 seconds. If CO levels remain above the set threshold after 15 seconds, the alarm will sound again until levels drop below the limit
• 【Large Capacity Battery & Fast Charging】The 3-in-1 carbon monoxide monitor has a 1000mAh Li-ion battery and supports 10–65W fast charging. With TYPE-C fast charging, it charges fully in just 1 hour (4 hours normally). After 5 minutes of inactivity, the CO detector enters low-brightness power-saving mode, providing up to 140 hours of standby time. Perfect for travel, camping, or outdoor activities
• 【Outdoor Lanyard & Magnetic Attachment】The travel carbon monoxide detector can be placed anywhere, like on a table in the living room, kitchen, or bedroom. It also comes with a handy outdoor lanyard for easy carrying during travel, camping, picnics, and outdoor adventures.
