Breathalyzers with upper limit indicator
prices on 15 modelsUpper limit
— the ability to operate the device with the established upper limit of the norm. If the measurement results do not exceed this value, the device will simply display them on the display, and if exceeded, it will give a warning signal. The limit of the norm, usually, the user can set at his discretion within the measurement range.This function is very useful in situations where you do not need to determine the exact content of alcohol in the blood, but only to check whether it is within the allowed level. And some advanced models with this function have advanced features and are able, for example, to control an electronic lock, opening it only if the result does not exceed the normal limit.
