Portable Carbon Monoxide and Carbon Dioxide Detector, 4-in-1 Magnetic Carbon Monoxide and Carbon Dioxide Detector, Audible and Visual Alarms, 3-Day Standby, Carbon Monoxide and Carbon Dioxide Monitor,

All-in-One Carbon Monoxide and
Carbon Dioxide Detector: The DS-100PRO monitors carbon monoxide (01000 ppm), carbon dioxide (4005000 ppm), temperature, and humidity. It triggers an alarm at 50 ppm CO or 1500 ppm CO2, ensuring early warning and comprehensive air quality protection
Portable and Compact: Lightweight and pocket-sized, featuring a lanyard and built-in magnet. It can be clipped to a backpack, hung inside a tent, or securely attached to metal surfaces. Once powered, it can operate continuously for up to 72 hours. Ideal for homes, cars, offices, tents, or travel
Dual Audio-Visual Alarms: Features a three-color indicator light (green/yellow/red) and a loud buzzer. Supports customizable alarm thresholds, allowing you to tailor safety parameters for different scenarios (such as homes, garages, tents, etc. )
Dual Gas Protection: Carbon monoxide (CO) detection helps prevent poisoning caused by malfunctioning heating systems, fireplaces, or vehicle exhaust, while carbon dioxide (CO2) monitoring indicates ventilation quality in enclosed spaces such as homes, indoor growing areas, or wine cellars, providing comprehensive protection against multiple hazards How to Properly Test for
Carbon Monoxide: Easily verify the detectors responsiveness by placing a small smoke source, such as burning paper or a cigarette, near the sensormaintaining a safe distance from the smoke or ash. The alarm should activate within seconds. Testing with vehicle exhaust or gas stoves is not recommended, as normal operation typically does not release detectable levels of carbon monoxide
