This 4-in-1 detector is a solid safety tool for any home.

It monitors carbon monoxide (CO), combustible gas (like propane or natural gas), temperature, and humidity – all in one compact plug-in device.

The HD color screen shows you real-time readings in PPM for CO and %LEL for gas, plus temp and humidity.

It's plug-and-play with standard US AC outlets (110-220V), and has a built-in 1000mAh rechargeable battery that keeps it running for up to 24 hours during a power outage.

That's a big deal – most basic detectors just go dead when the power goes out.

The sensors are highly sensitive and accurate.

It'll trigger an 85dB audible alarm and flash a red light when CO hits dangerous levels (above 150ppm) or gas reaches the alarm threshold.

It also has voice alerts, so you're not just hearing beeps – you know exactly what's happening.

Use it in bedrooms, kitchens, garages, basements, or even RVs.

It's great for fireplaces, gas appliances, or anywhere there's combustion.

The screen is easy to read at night, and the device is compact enough not to block other outlets.

Just remove the protective film before use, let it calibrate for 120 seconds, and test it with the self-test button.

Reliable, affordable, and gives you peace of mind.
