So, you get drunk often and sometimes you even being charged with driving while intoxicated. To make sure this won’t happen again having your own Breathalyzers is a great idea. Drinking and driving are highly dangerous and by doing this you are risking you and others living on the road. So be a responsible driver and make sure your limit before riding by your own personal breathalyzer.
What are Breathalyzers? And how does it work?
They are small gadgets made to test how much alcohol is in your breath. When a person consumes alcohol, it gets absorbed into bloodstreams through mouths stomach and throat which shows up in the breath.
When a person exhales into Breathalyzer, ethanol present in breath oxidizes to acetic acid at the anode and at the cathode atmospheric oxygen is reduced.
This overall reaction us oxidation of ethanol your acetic acid water. The electric current produced by this reaction is measured by the microcontroller which shows up as bold alcohol content.
Types of Breathalyzers-
There are three main types of Breathalyzers.
Electrochemical Fuel Cell Analysis-
These devices use electric current to detect the alcohol level. Fuel cell contains two electrodes one of gold and platinum. When personally exhales their breath at Breathalyzers Ethanol oxidizes into acetic acid water. The more electrons will produce the more the current will produce. Then this current is measured by the microcontroller and displayed on display. The fuel cells are very small and need less power to work that’s why they are suitable for the long term.
Infrared Optical Sensor Analyzer
These devices measure infrared light in molecules that present in the air.
Ethanol molecule absorbs a certain wavelength of infrared radiation. The more of wavelength is present the more alcohol in the sample. Photocell present in the infrared waves produces an electrical pulse which depends on how much of the wavelength of infrared has been absorbed. Microcontrollers present in the device measures the current and gives a reading. These devices are the most accurate results and work for many years until they are calibrated.
These breathalyzers contain semiconductor which produces current. when Alcohol reaches the semiconductor, it will alter the resistivity and change the current. The more changes show by the conductor the more alcohol present in the breath sample. But results are affected by climate altitude and cigarette. They are widely used because of their cheap.

FAQ about Breathalyzers:
Why do I need a Breathalyzers?
Breathalyzer Is a device that measures the alcohol content in our blood. It ensures the safety of a person and other people. By measuring their BAC, they can aware of their condition and save themselves from accidents.
What is the limit for Blood Alcohol Count?
Across the U.S. in all states except Utah, it is illegal for any person 21 years or older to drive a vehicle with a BAC of 0.08%. In 2018 Utah changed its laws and make it illegal to drive vehicles with a BAC of 0.05% for a person 21 years or older.
What is BAC?
Blood Alcohol Count is the concentration of blood present in the person’ s blood. It is a unit for intoxication used for legal or medical purposes. It is measured as mass per volume. For example, BCA of 0.05% means 0.05 grams of alcohol present with respect to 100 grams of a person’s blood.
Is it safe to drive if my BAC is under the legal limit?
Breathalyzers only for informational purpose please don’t misuse the device any amount of alcohol consumption affect reflexes, motor skill and cognitive abilities. You will not only risk your life but others’ life on the road.
What types of procedures required to maintain a personal breathalyzer?
All breathalyzers required calibration after some time. Now the question is what is calibration? It is a process of checking and adjusting the accuracy of a unit. For example, if a concentration of 0.008 is blown into the breathalyzers then the unit is adjusted to make sure that result will come 0.080%.
How often should I calibrate my Breathalyzers to ensure accuracy?
Breathalyzers with semiconductors’ sensors needs to be calibrated after every 300 tests or once a year. Breathalyzers with fuel-cell sensors remain accurate till 2000 tests after that you need to be calibrated.
What is the difference between personal and professional Breathalyzers?
Professionals Breathalyzers use fuel- cells sensors Which provide more accurate results than semiconductor sensors. They are more accurate at higher BAC concentrations. Professional Breathalyzers show results up to thousandth decimal place while personal shows up to the hundredth decimal place.
They do not show false results for someone who is diabetic or on a low-calorie diet. But semiconductor sometimes shows a false-positive result for these individuals.
They can remain accurate up to 1000 tests and semiconductors remain accurate up to only 300-400 tests.
Which Breathalyzer model should I buy?
If you want more accurate results, I advise you to go for a professional one maybe it cost you extra money but it worth it. Buy a Breathalyzer with fuel -cell sensor these devices use the same technology used by the law and medical agencies.
If you only want the device for alcohol detection then you can by Breathalyzers with semiconductor sensors they will not give you accurate results but satisfactory results and also, they need to be calibrated in short times. But they are cheaper and affordable than professional breathalyzers.
