Portable carbon monoxide detector, emergency flashlight, thermometer and hygrometer for camping, travel, car and kitchen

Multifunctional Detection: The carbon monoxide detector monitors CO concentration (0-1000 ppm), ambient temperature (-10-55°C), and humidity (0-100% RH) in real time, meeting both home and industrial safety needs.

Four-Level Audible and Visual Alarm: The carbon monoxide detector features a four-level audible and visual alarm (green/yellow/orange/red), accurately displaying dangerous concentrations of carbon monoxide in the air in real time. If the limit is exceeded, an alarm will sound immediately.

Extremely Long Battery Life: The built-in 2000mAh lithium battery provides 300 hours of continuous use on a full charge. The carbon monoxide detector automatically enters power-saving mode after one minute of inactivity.

Practical Design: A built-in emergency flashlight (high/low brightness modes) makes it easier to use at night. The temperature unit can be switched between Celsius (°C) and Fahrenheit (°F), ensuring accurate and reliable data.

High-Accuracy Detector: This carbon monoxide detector features a precise sensor that quickly detects ambient CO2 concentrations. It's ideal for ensuring air quality and safety in poorly ventilated indoor spaces, such as garages, fireplaces, or gas heaters.
