This alcohol breathalyzer uses a patented technology called the BluFire Fuel Cell Sensor which is the same method relied on by law enforcement and medical agencies. It can be used on its own when the results are displayed on its bright and clear OLED screen. It can also be used with a smartphone via a Bluetooth connection and an app which will display your results on your phone.
You will get your alcohol level results as well as an estimate of how long it will be before your BAC is back to zero. It’s small and very portable and easily fits in a pocket or purse.
