Meet the Lwuey Portable 4-in-1 CO Detector

Compact, lightweight, and built for everyday safety, this 4-in-1 monitor blends carbon monoxide detection with humidity and temperature sensing, plus a built in flashlight. It serves as a versatile environmental companion for travel, home, camping, and more. This is a consumer safety monitor, not a medical device.

What it measures

The device detects carbon monoxide from 0 to 1000 ppm, humidity from 0 to 100 percent RH, and temperature from 14 F to 131 F. Readings refresh every 3 seconds after startup, so you get a near real time sense of air conditions.

• 4-in-1 functionality: CO, humidity, temperature, and illumination
• Built in flashlight up to 100 lumens for low light environments
• Audible and visual alarm that scales with CO concentration

Performance and indicators

Color coded feedback helps you gauge risk at a glance: green for low, yellow for low-to-moderate, orange for rising levels, red for high. The device starts monitoring in about 35 seconds.

• Four color zones map CO levels from 0 to 1000 ppm
• Audible alert pattern increases with concentration
• Data refreshes every 3 seconds to keep readings current

Portability and power

Designed for travel and tight spaces, the detector measures 3.8 x 2.2 x 1.2 inches and weighs 0.35 lb. A 2000 mAh battery powers the device, with USB-C charging that takes about 3 to 4 hours. It offers up to 300 hours of standby time when idle.
