Details

Detects CO, natural gas, propane & temperature. Live digital display. Plug-in. Works on both 110V and 220V outlets. Pairs perfectly with an RV inverter — runs continuously as long as your inverter is on. 3-year sensor life.

How It Works

Plug into any RV outlet. Screen shows live air readings around the clock. If levels rise, it alarms before you feel any symptoms — even while you sleep.

Safety & Placement

Place near your sleeping area for overnight protection. Keep at least 5 feet away from propane appliances, the stove, and generator exhaust. Avoid mounting directly above the stove or in enclosed storage compartments.

How is this different form a standard a standard detector?

Standard detectors use outdated Grade 1 sensors — the green light only means it has power, and the test button only checks the speaker. You have no idea if the sensor is actually working. Dewlora uses a Grade 3 sensor, detects faster, and shows real numbers on a live display so you always know exactly what's in your air.

Why the detector in your RV falls short

Most RVs ship with a basic CO detector. It shows green. It beeps if things get bad enough. But by the time it beeps, you may already be in trouble.

What Your RV detector misses

green light confirms power, not safe air

most alarms react only at higher thresholds

CO-only — won't detect a propane leak

Sensor degrades silently over time

No display — you never know what's actually in the air

How Dewlora helps

shows live gas readings directly on screen

helps you spot rising levels from 30+ ppm

detects carbon monoxide, natural gas, and propane

Sensor health indicator — always know it's working

Helps protect your family earlier on the road

Carbon monoxide builds quietly inside an RV — especially when a generator is running nearby.

What earlier visibility changes

Carbon monoxide can build quietly. When Dewlora helps you see rising levels sooner, you and your family have more time to ventilate, investigate, and respond before a late alarm becomes the first warning.

Visible readings, broader detection, and earlier awareness create a more trustworthy safety experience than a status-light-only detector.

The science behind Dewlora

1 / 3

Measured, not assumed

Dewlora combines live PPM visibility with CO, natural gas, and propane detection — so RV owners understand risk earlier instead of waiting for a late alarm threshold.

The science behind Dewlora

2 / 3

Broader than CO alone

Your RV runs on propane — fridge, stove, water heater, furnace. A CO-only detector won't see a propane leak. Dewlora detects both, so you're covered for every gas risk in your rig.

The science behind Dewlora

3 / 3

Earlier point of awareness

Visibility before the alarm threshold means you and your travel partner have more time to act — open a vent, shut off the generator, get outside. That time is everything.

What changed after switching to Dewlora

“Our old detector showed green for years. Dewlora showed a real number the first day, and that changed how we think about the whole house.”

Dr. Jameson

“We installed one in the kitchen and another near the boiler, and it’s been incredibly reassuring. Setup was simple, and the readings are clear at a glance.”

Lisa Whitmore

“I bought multiple units because one hallway alarm was not enough. I wanted my mother to have visible readings in more than one room.”

Danna M

“I bought multiple units because one hallway alarm was not enough. I wanted my mother to have visible readings in more than one room.”

Sarah K.

"Been full-timing for 4 years and never thought twice about the stock detector. First night with Dewlora it showed 18 PPM. Turned out my propane water heater had a small leak. The old detector never made a sound. This thing paid for itself on day one."

Gary M. - Full time RVer

"My husband and I travel every winter in our fifth wheel. I bought this after reading about CO deaths in RVs. It shows zero every morning and I check it before I even make coffee. The peace of mind alone is worth every penny. Wish we had it years ago."

Danna M - Seasonal RVer

"I run a generator at night when it's cold. Always worried about CO creeping in. This detector gives me actual numbers so I know exactly what's happening. Showed 4 PPM one night — totally safe but at least I knew. My old detector just sat there with a green light telling me nothing."

Lisa Whitmore - Retired RVers

"Our daughter bought us this after seeing something about CO in RVs online. We thought she was being overprotective. Then it alarmed at 42 PPM our second night at a new campsite — generator exhaust was getting in through a vent. We had no idea. We owe her one."

CO DEATHS ANNUALY

CO exposure remains a serious risk for every household and RV owner

Don’t wait for the
alarm to catch up.

Generators are the #1 source of CO poisoning deaths in the US. The real risk is believing you're safe because your detector shows no warning — when it's only waiting for things to get bad enough to beep.

Built with firefighter insight. Built for the road.

Firefighters respond to CO incidents at campgrounds and RV parks every season. The pattern is always the same: a generator running nearby, a cheap detector that never alarmed, a family that didn't wake up in time.

Frequently asked questions

Does it detect natural gas and propane, or only CO?

It detects all three — carbon monoxide, natural gas, and propane. Most RV stock detectors only cover one or two. Dewlora covers everything running in your rig.

Will it work while I'm running on inverter power?

Yes — as long as your inverter is on and powering the outlet, Dewlora runs continuously. It requires a live outlet to operate.

Where should I place it in my RV?

Near your sleeping area is most important. Keep it at least 5 feet from propane appliances and the stove to avoid false alarms. Do not place it in enclosed storage compartments.

My RV already has a built-in CO detector — why do I need this?

The stock detector in most RVs uses an outdated Grade 1 sensor and only alarms at 70 PPM — brain damage starts at 40. It also shows no readings, so you never know what's actually in your air. Dewlora uses a Grade 3 sensor, alarms earlier, and shows live numbers 24/7.

How long does the sensor last?

3 years. After that the sensor degrades and should be replaced — just like any CO detector.

Is it difficult to set up?

No — plug it into any standard outlet and it starts monitoring immediately. No app, no Wi-Fi, no setup required. Takes about 10 seconds.
