How Does a Breathalyzer Work?

How does a breathalyzer work? A hand-held gadget will be placed in front of the person’s mouth, and the driver will be asked to breathe into it. This will reveal whether or not the person has consumed any alcohol in recent time. A breath screening test will be needed if any alcohol content is found. It will then be necessary to take a breathalyzer test. It is at this point the law enforcement officer will hand the driver a tiny electronic gadget and instruct the driver to breathe into it. They will be requested to take an evidentiary breath test or a blood sample if the user’s Blood Alcohol Concentration (BAC) level is high. The measurement is made by detecting tiny amounts of alcohol excreted by the body through the lungs. Even though there can be fluctuations among persons because of varied sizes, weights and health conditions, BAC is around 2,300 times breath alcohol concentration. Alcohol level can be detected from the air expelled from our lungs and breath testing devices employ heat transfer and infrared absorption techniques to determine this. A breath alcohol plan is an effective technique in several scenarios, including but not limited to law enforcement officer’s checkpoints for drivers. 

Breathalyzers Continue to Advance in Technology

How does a breathalyzer work? In recent times, technology has enabled a breathalyzer that detects marijuana and determines how intoxicated a person is using extraordinary responsiveness. The new gadget is far more precise than breathalyzers, which test for blood alcohol concentration levels. Experts dubbed the new instrument a “game-changer” in the effort to eradicate driving while under the influence of the drug. Blood tests can detect marijuana up to 30 days after use, but this new screening method can detect it in only just a few hours when someone has consumed or ingested it over the last few hours. 

Importance of a Breathalyzer

People are often curious about how does a breathalyzer work but mostly people just want to know that it does work.  They want to ensure their own safety and that of other people.  Police, professional and personal breathalyzers give a strong indication of the level of alcohol in a person’s system and allows them to make an informed choice on whether to drive or not.  Even if the BAC is below the legal limit, it is best to appreciate that if you feel even slightly affected not sure whether to drive or not, sometimes the best decision is to leave the car and find another way home.
