The Breeze breathalyser is very light, weighing only 30 gm, and because of its size fits easily in the pocket. The user blows into the mouthpiece and an electro-chemical fuel cell breath sensor with Fluid Dynamics (patent applied for) sends the blood alcohol level readings immediately to an App. The Breatho-meter App can be used to order an Uber, local cab, call a friend or even find a hotel nearby. For the user’s own reference the App also records the previously measured values.
