ByAnciel 4-in-1 CO & Natural Gas Alarm with 2.1" LCD | Backup Battery

Your everyday air awareness companion

Meet ByAnciel s 4-in-1 plug-in CO and natural gas alarm, a compact device designed to stay out of the way while keeping you informed. The built in 2.1 inch color LCD renders multiple readings at a glance, including combustible gas concentration, CO in ppm, temperature, and humidity. Its clean, unobtrusive form fits neatly in kitchens, living spaces, and travel cabins, while the integrated backup battery adds resilience when power is interrupted.

Real-time readings you can trust

The device gathers two gas metrics and two environmental values on a single screen. CO readings cover a wide range up to 2000 ppm, while natural gas concentration is shown up to a practical 10 percent LEL. With distinct icons and a bright display, you can quickly gauge changes as you cook, ventilate, or move between rooms without squinting at small numbers.

• Multi function display for gas concentration, CO in ppm, temperature, and humidity with intuitive icons
• Vivid color LCD delivers clear numbers and symbols for fast interpretation
• Instant alerts inform you when readings shift toward higher or unusual values

Setup, power, and portability

Powered by a built in 1000 mAh battery, this detector may continue to operate during power outages and can be used as a portable detector for outdoor spaces or temporary setups. When plugged in, it remains compact and easy to reposition as your space evolves.

• Plug in and remove the protective film from the screen before first use
• After connecting to power, allow about 180 seconds for initial calibration
• Use the test button to confirm audible and visual alarm functionality
• For the most accurate temperature and humidity readings, allow roughly 30 minutes of continuous monitoring

Versatile placement for daily life

With its small footprint, the detector works well in homes, RVs, hotels, kitchens, and cruise cabins. The white finish blends with most interiors, while the built in backup battery supports short term usage away from an outlet. Its design invites placement near activity zones where air conditions can change with cooking, heating, or ventilation.

Note the device is designed to provide visibility into air conditions and to react to shifts with alerts. It is a helpful part of daily awareness but should be used in conjunction with proper ventilation and safety practices.
