Breathalyzer with Fuel Cell sensor…Don’t worry, we’re not NASA 🙂

There is no complicated language. The objective is to help you make a well informed choice on your next (or first) breathalyzer.

There are many breathalyzers on the market, but few can be considered reliable.

Even those are not all the same.

Among portable breathalyzers, there are those that use semiconductor technology, and those that use fuel cell sensors.

For example, the breathalyzers used by law enforcement predominantly use fuel cell technology. These measuring devices are extremely sensitive and selective for ethanol, which is the substance that allows for identifying and measuring the level of alcohol

On the other hand, semiconductor breathalyzers are much less selective for ethanol, thus there are some tricks that may actually yield false readings in semiconductor breathalyzers.

This is one of the reasons why law enforcement, occupational doctors, authorized personnel, and obviously all FLOOME products, use fuel cell-type sensors.

For more in-depth information on fuel cell sensors, you can read our article on how breathalyzers work.

Simply put, this sensor is highly selective for ethanol. A breathalyzer based on this type of sensor is typically very accurate, precise, allows for repeatable values, and maintains these characteristics for an extremely long time in comparison to, for example, a semiconductor-based breathalyzer.

In addition, this type of breathalyzer category is much more sensitive to ethanol variations, and the device generally performs better even for high alcohol levels. This type of breathalyzer is therefore, essential to also test alcohol levels close to legal limits.

FLOOME offers breathalyzers that exclusively use platinum fuel cells, thus making their precision, accuracy, and repeatability of values, highly reliable over time.
