Have you ever been in a situation where you had a drink or two more than you should have? Maybe you had a few beers before going partying, or you drank a few shots after a long day at work. Whatever your situation, it’s important to know how much alcohol you’ve consumed. An easy solution to this problem is to use a breathalyzer. These devices can be used to quickly detect your blood alcohol concentration and let you know that the amount you have consumed is safe. They are also useful for drivers looking to avoid driving under the influence.
What is a breathalyzer?
A breathalyzer is a device that measures the blood alcohol content of a person, usually through the process of taking a breath sample. It is used in many jurisdictions as a legal device to measure intoxication in cases of suspected driving under the influence. The breathalyzer is designed to measure the amount of alcohol in the user's breath. It is a chemical instrument used to measure the alcohol concentration in breath and is intended for use by law enforcement agencies and other personnel to determine the level of blood alcohol content of a person who has been drinking.
How does a breathalyzer work?
A breathalyzer tests for your blood alcohol concentration by measuring the amount of alcohol in your breath. It does this by using a carbon dioxide sensor. The breathalyzer has a mouthpiece that you put in your mouth, and you blow into the unit. The sensor will then measure the amount of alcohol in your breath. It will then calculate your alcohol concentration based on the amount of alcohol in your breath.
It works so well due to the way our bodies process alcohol
- When alcohol enters our mouths, it moves down to the stomach and intestines, and then it gets absorbed into the blood. During this process, the alcohol molecules do not change and continue to the rest of the body.
- When the molecules get to the lungs the action of breathing will exhaust the molecules and that's when a foul odor is noticeable. This is why one can tell if a person has been drinking an alcoholic beverage.
- Since the concentration of molecules in the lungs is almost the same as in the bloodstream, the action of exhaling is enough for the breathalyzer to pick the concentration of molecules. Therefore, depending on the accuracy of the breathalyzer it will provide the BAC number.
How to use a breathalyzer?
The best breathalyzers to use are the smartphone breathalyzer app. It is easy to use, portable, and will give you a fast and accurate reading. The best app is called Breathometer. It has a lot of cool features that make it the best app, such as the ability to share your readings with friends. It also has a lot of cool features for people who are sober and for people who are not sober. It is the best app for anyone looking for a breathalyzer.
Types of breathalyzers
There are mainly three types of breathalyzers for personal use. These units are not in the same league as what the professionals normally use, never the less they provide fairly good readings to give you an idea of how badly you are intoxicated.
As the more expensive machines these lower-priced breathalyzers need to be calibrated periodically.
Fuel cell sensor units
When it comes to having more accurate readings the fuel cell sensor breathalyzer is the one to have for home and/or personal use. But there is an issue that this unit needs, and that's regular calibration by the manufacturer which adds to the cost of having one.
Apart from the extra costs of calibration, this unit has a higher purchase price than other units with other technologies.
Our best pick is the BACtrack S80 Breathalyzer which uses the fuel cell sensor technology.
Semiconductor Oxide Sensor
Being relatively new, this detector seems to be the best thing currently available.
This is the latest and greatest that uses semiconductor technology to detect your BAC. Therefore, making this breathalyzer cheaper to produce and hence cheaper to buy but their main problem is that they are not highly accurate.
Therefore, this unit will never be used by professionals so will only be used for personal use.
Infrared Spectrometer
These breathalyzers are on a different level from the personal and home-used units. They are not portable like the smaller ones mentioned above and are used by professional services like hospitals, police stations, and other identities that require them for legal purposes. These are a lot more technical and work by identifying the molecules in one's breath.
Apart from being more expensive, they are very accurate, therefore, it wouldn't make sense to have one at home when a cheaper and close enough test may be sufficient.
Due to the cost and size, these units are not normally sold to the public for home or personal use. They are normally available for professional services to exactly identify the amount of alcohol one has in the blood.
Disposable units
These units are cheap but not that reliable, the main purpose is to find out if one has been drinking alcohol. After use, it's a throw-away because it's only made for a one-shot test.
What are the negatives of using a breathalyzer?
There are no negatives, bad practices, or misunderstandings as to why not to use a personal breathalyzer.
Keep in mind that when you are close to the limit of alcohol content and you decide to drive the results from a personal breathalyzer may not free you from being charged with DUI.
A breathalyzer is a very safe (i.e. no pain, or side effects), and easy test to do. A portable breathalyzer, like a chain breathalyzer, would be ideal for a quick test.
Conclusion
If you want to get an idea of how intoxicated you are, you can purchase a breathalyzer. These handy devices provide a quick and easy way to test your alcohol concentration. They are very affordable and can be found at any store. They are also easy to use. You simply blow into the mouthpiece and the device will give you a reading. You can use a breathalyzer to find out if you are over the legal limit so that you can avoid a DUI. As a general rule of thumb, the higher the alcohol concentration, the more accurate the reading. The reading will be most accurate if you take your alcohol concentration at a time at which you are not actively drinking. This will help you avoid any false readings.
