4-in-1 Air Quality Detector: This portable CO detectors measures CO (0–999 ppm), CO₂ (0–5000 ppm), temperature (approx. 40–176°F), and humidity (0–99% RH), updating every 2 seconds
Ultra-Long Battery Life: Built-in 1000 mAh rechargeable battery with Type-C fast charging. Provides up to 240 hrs continuous monitoring and enters power-saving mode after 1 min, still detecting CO — ideal for travel and off-grid use
Portable & Easy to Mount: The CO detector is compact and lightweight. Hang it on backpacks or tents with the lanyard, or attach it to cars, refrigerators, or other metal surfaces with the built-in magnet. Comes with a zippered case for easy carrying
Customizable Alarm Thresholds: The travel CO₂ detector lets you set CO (5–995 ppm, default 50 ppm) and CO₂ (500–5000 ppm, default 700 ppm). Exceeding levels triggers a loud 85 dB alarm and shows yellow or red bars on the screen according to severity
Easy to Operate: Press and hold 1s to power on/off. Press once to switch CO/CO₂, twice to turn alarm sound on/off, three times for custom alarm mode (CO or CO₂ settings), four times for °C/°F, five times for CO₂ calibration
