5 Best Breathalyzer Review

In this review I am going to tell you about 5 best breathalyzer which can be used for testing a driver's BAC level.

If the term Breathalyzer is new to you, no worries. Below I have explained in brief what is a breathalyser and how it works.

What Is A Breathalyzer?

In simple terms, a breathalyzer is a device for estimating blood alcohol content (BAC) from a breath sample.

It is also known to many as alcohol breath testers or alcohol testers.

Blood Alcohol Concentration (BAC) is the legal terminology used for determining Alcohol Intoxication level.

How Does A Breathalyzer Works?

When alcohol is drunk it gets absorbed into the bloodstream through the mouth, throat and stomach and hence, shows up in the breath.

In the bloodstream, alcohol is neither digested via absorption nor does it get chemically changed. 

As alcohol is volatile, in the lungs some amount of it moves across the air sacs membrane into the air.

When this alcohol concentrated air is exhaled, a device like breathalyser can easily detect it.

Thus, it is more convenient for an law enforcement officer to use a breathalysers for testing a driver’s BAC level.

Why A Breathalyzer Is Used?

The Breathalyzer is used by almost all law enforcement agencies for testing BAC.

Why it is used?

For law enforcement agencies taking a blood sample of the suspected drunk drivers and sending it for checking in the lab is impractical, inefficient and time-consuming.

Thus, to establish drunk driving on the spot, breathalyzer comes handy.

Should You Buy A Breathalyzer?
