How Breathe Sentinel™ Detects Hidden Gas Dangers Before They Become an Emergency

Carbon monoxide and combustible gas can build up in your home without obvious warning. You can't see carbon monoxide, and certain gas leaks may be difficult to notice before concentrations become dangerous.

 

That's why simply relying on your senses isn't enough.

 

Breathe Sentinel™ continuously monitors carbon monoxide and combustible gas levels while also tracking temperature and humidity in real time.

 

Its high-precision sensors and clear color LCD display help you stay informed about what's happening in the air around you.

 

Instead of wondering whether your home is safe, Breathe Sentinel™ gives you the information and alerts you need to respond when abnormal levels are detected.

One Device. Multiple Layers of Safety.

Breathe Sentinel™ combines smart monitoring, clear readings, and responsive alerts to help keep your home informed and protected.

Real-Time CO Monitoring

See carbon monoxide levels displayed in PPM on the large color LCD, helping you stay informed about changes in the air around you.

Clear Color Display

See CO, gas, temperature, and humidity readings together on one high-definition LCD screen that's easy to read at a glance.

Live Gas Detection

Monitor combustible gas levels in %LEL with a dedicated catalytic combustion sensor designed to provide responsive gas detection.

Temperature & Humidity

Track temperature and relative humidity in real time alongside your gas readings giving you a more complete picture of your indoor environment.

Introducing: The Breathe Sentinel™ CO & Gas Detector

Breathe Sentinel™ is an easy-to-use 4-in-1 detector designed to give you real-time readings for carbon monoxide, combustible gas, temperature, and humidity — all from one compact device.

 

Its high-precision sensors and large color LCD display make it simple to monitor your indoor environment and stay informed when detected levels change.

 

With adjustable sound and brightness controls plus optional 9V battery backup, Breathe Sentinel™ is designed to provide reliable monitoring throughout your home.

 

Because you shouldn't have to wait for danger to become an emergency before you know what's happening. Gasfence™ helps you see it sooner.

A threat you’ll never sense

No color. No smell. No obvious warning — Breathe Sentinel™™ helps you monitor CO and combustible gas levels in real time, so you’re not relying on your senses alone.

You can’t see it. You can’t smell it. And you may not know it’s there.

Carbon monoxide is a colorless, odorless gas that can come from fuel-burning appliances such as furnaces, water heaters, stoves, fireplaces, and vehicles. Without reliable monitoring, dangerous levels can build up before you realize there's a problem.

Know what's happening as it happens

You shouldn’t have to wait for a basic alarm to tell you that something has changed. Breathe Sentinel™ continuously monitors carbon monoxide and combustible gas levels, giving you real-time visibility into what’s happening around you.

 

Powered by responsive electrochemical and catalytic combustion sensors, Breathe Sentinel™ is designed to detect changes and trigger clear audible and visual alerts when monitored concentrations reach its alarm threshold.

 

With the large color LCD, you can see CO and gas readings at a glance along with temperature and humidity so you’re not left guessing about the environment inside your home.

Title

What does Vaporivo detect?

Vaporivo monitors carbon monoxide (CO) and combustible fuel gas levels, while also displaying temperature and humidity in real time.

How does Vaporivo alert me to danger?

When detected CO or gas levels reach the device’s alarm threshold, Vaporivo provides audible and visual alerts to notify you.

Can I see the gas and CO levels in real time?

Yes. The large color LCD displays CO concentration in PPM and fuel gas concentration in %LEL, along with temperature and humidity readings.

Does Breathe Sentinel™ work during a power outage?

Yes. Breathe Sentinel™ supports a 9V battery backup option, allowing the detector to continue operating when installed with a compatible 9V battery. The battery is not included.

Can I adjust the alarm volume?

Yes. Breathe Sentinel™ features three adjustable sound levels, allowing you to choose the volume that suits your environment.

Why should I choose the 3-Pack?

A single detector only monitors the area where it's installed. The 3-Pack lets you place Breathe Sentinel™ in multiple important areas of your home, such as bedrooms, kitchens, living spaces, or garages, for broader coverage.

What information can I see on the display?

The large color LCD can show CO levels (PPM), fuel-gas levels (%LEL), temperature (°F), and humidity (RH%), giving you multiple readings in one place.
