This time period includes the transit time for us to receive your return from the shipper (5 to 10 business days), the time it takes us to process your return once we receive it (3 to 5 business days), and the time it takes your bank to process our refund request (5 to 10 business days).

The CHENGHEM 3-in-1 Carbon Monoxide Detector is a compact plug-in device that brings three essential readings into one clear view: carbon monoxide levels, temperature, and humidity. Designed for everyday spaces and for travel, it starts monitoring quickly after you plug it in, so you can see the surrounding air conditions at a glance without extra setup.
Powered by a highly sensitive electrochemical CO sensor, this detector covers a CO range of 0-1000 ppm and delivers a fast audible alarm when levels shift. Alongside CO data, the dedicated temperature and humidity sensor provides a real-time snapshot of the environment, helping you interpret readings and adjust airflow or ventilation as needed.
From bedrooms to kitchens and living areas, this detector fits a wide range of spaces. It’s also well suited for RVs, hotel rooms, and offices, making it a versatile addition to homes and travel kits alike.
With a straightforward plug-and-play design, there’s no wiring or replacement batteries to worry about. The unit sits neatly in a standard outlet, keeping the surface space uncluttered while delivering constant monitoring and audible alerts when needed.
In addition to reliable monitoring, CHENGHEM offers a responsive support experience and a 90-day return window for peace of mind. If you have questions, you can reach out by email and expect a helpful reply aimed at solving the issue quickly.
