How Does the Breathalyzer Work?

When you drink, it goes into your small intestine via the stomach. From the stomach, alcohol gets absorbed into your blood and then passes on to other body parts, including the brain and lungs. After alcohol reaches your lungs, you exhale it when you breathe.

The breathalyzer measures how much alcohol is in the air you breathe out and therefore how much alcohol is in your blood. The measure is known as your BAC (Blood Alcohol Content).

If your BAC is above 0, then you are certainly not in the condition of driving and must wait for at least 24 hours before getting behind the wheel of a car. The BAC limit as per the law is 0.08 in the USA.

Here we have a Youtube video that shows the science behind breathalyzer.

What Are the Benefits of a Breathalyzer?

Alcohol detectors are frequently used in social gatherings or police officers to ensure strict control over impaired driving. But you can also use one at home to ensure you are not drunk to drive. Some of its various benefits are:

  • While drinking, it is challenging to keep a check on your alcohol level, leading to risky decision-making. Hence, it’s advisable to keep a breathalyzer to monitor the alcohol level and make an informed decision about driving and acting responsibly.
  • The device will help you stay within the legal limits and keep you away from getting penalized. The portable breathalyzers are ideal for those who wish to drink in social gatherings and not drive if the alcohol level is more than the legal limit.
  • A breathalyzer gives accurate results that are equivalent to a blood sample report. Blood sampling can be a daunting task for those who fear needles. Hence this is a more effective way of getting the test done.
  • The users get instant results from the device, and they can then immediately take preventive measures.
  • This is an inexpensive way to stay away from problems compared to the fine you need to pay.

Upgrade version

Look for the latest version of your product. An upgraded version may include a lithium battery that lasts for a longer duration, which allows at least 800-1000 tests. Also, the device should automatically turn off to power saver mode after the test is over.

Smart alarm function

A few devices allow the user to set BAC based on their own need. If the test result is higher than the set BAC alarm rings or the breathalyzer flashes’ red light to remind the user. If you need to drive after drinking, it stops you from consuming more alcohol.

Warm-up, blowing, and reset time 

If you wish to do multiple testing on the same night, make sure that your breathalyzer gets ready for the next test almost immediately. Also, it must give accurate results after every reset. It should take very little time to warm up after you switch it on and have a short blowing time of just a few seconds.


Ensure your device is easily portable and convenient to store. It should also occupy significantly less space in your handbag, which you can carry in a party or public gathering.
