Why it fits your life

• 3-in-1 sensing: monitors CO levels, temperature, and humidity to help you understand your environment at a glance.
• Customizable alerts: set your preferred CO threshold and receive immediate warnings when readings drift into potentially concerning ranges.
• Audible and visual alarms: a loud alarm and on-screen indicators work together to grab your attention when action may be needed.
• Night-visible design: translucent housing with glowing indicators lets you see warnings in dark rooms without turning on lights.
• Portable and versatile: slim, lightweight build (54 x 27 x 110.2 mm) plus an outdoor lanyard and built-in magnet for easy placement at home, in the car, or on the go.
• Long-lasting power: a 2100 mAh rechargeable battery with Type-C fast charging delivers up to 150 hours of continuous monitoring, reducing the need for frequent battery changes.

Real-life use and scenarios

• In the home: place Watcher-S1 on a counter or mount it near sleeping areas to keep an eye on CO levels while you rest.
• Ahead of travel: pack it in luggage or attach to a backpack for hotel rooms, campers, or RVs where air quality varies.
• In transit: keep it close in cars or tents where portable monitoring helps you stay informed during trips and outdoor adventures.
• During power outages: the night-visible ring helps you detect changes in ambient conditions when lighting is limited.

How to use and maintain

Before first use, allow the device to stabilize in a calm environment and check readings periodically. The Watcher-S1 is designed for quick setup and trouble-free operation, with a focus on constant awareness rather than alarms alone. Remember to follow the included guidance for testing and placement to ensure reliable readings over time.
