Breathalysers and breathalyzers

Breathalysers and breathalysers are devices that allow you to determine the approximate concentration of alcohol in your blood. Breathalyzers are single-use products that do not determine the exact amount of promils in the blood - they only help to determine by means of a change in color or its intensity, whether it is legal to drive a car at a given moment (after drinking alcohol). Some of them additionally inform you if the 0.2‰ limit has been exceeded. Breathalysers, on the other hand, are reusable devices that allow you to determine the amount of promils in the blood, depending on the device - in a more or less accurate way. Semiconductor, electrochemical and spectrophotometric breathalysers are available on the market.
