A carbon monoxide (CO) detector helps protect against carbon monoxide, a toxic, odorless gas produced by incomplete combustion. A carbon dioxide (CO₂) monitor measures CO₂ levels to help users understand indoor ventilation conditions. Some monitors measure both gases, but a CO₂ monitor cannot replace a dedicated CO safety alarm.

The right monitor depends on what you want to measure. A CO alarm addresses carbon monoxide safety, a CO₂ monitor helps track carbon dioxide levels, and a radon monitor measures indoor radon concentrations. For particulate matter or VOCs, choose a device specifically designed to measure those pollutants.

For RV safety, carbon monoxide monitoring is essential when fuel-burning appliances or equipment may create a CO hazard. Depending on your RV's appliances, a suitable combustible gas detector may also be important. A CO₂ monitor can provide additional information about indoor ventilation, but it does not replace a CO alarm.

Radon is a naturally occurring radioactive gas that can enter buildings from the ground and accumulate indoors. Because it cannot be seen or smelled, testing is needed to determine its concentration. A radon monitor can help track indoor levels over time and support informed decisions about further testing or mitigation.

A gas detector is designed to detect specific gases, such as carbon monoxide or combustible gases. An air quality monitor measures selected indoor environmental parameters, which may include CO₂, particulate matter, VOCs, temperature or humidity. Always check the product specifications to confirm exactly what each device measures.

No. App connectivity depends on the model. Some FABISENSE monitors display readings directly on the device, while compatible Bluetooth or Wi-Fi models may offer historical data, trend charts or notifications through an app. Check the individual product page to confirm available features.
