Breathalyzer: What is the best of 2021?

We hope you enjoy your stay, and avoid drinking alcoholic beverages while reading, as our subject today is the breathalyzer.

Also called an alcohol meter, it is a device that you have surely heard of. It became popular after the approval of Federal Law No. 11,705 / 08, known as the Dry Law. It limits the amount of alcohol in any automotive vehicle driver’s test to zero.

Respecting the laws is important. But also understanding the limits of the equipment and its operation are also. After all, there are several product options and here we will inform you about everything you need to know.

First, the most important

  • Some medications have a specific alcohol content, even the chemical reaction in the digestion of some foods releases alcohol. For this reason, you may not be as safe from the breathalyzer positive as you believe.
  • Many breathalyzer options appeared on the market after Prohibition, mainly for domestic use. They are good options to help you, but read the product instructions very well. A silly mistake can cost you dearly.
  • It is important to remember that a measuring equipment needs to be calibrated and verified. Always look for the INMETRO inspection seal on the equipment you purchase.

Buying Guide

You already know how much having a breathalyzer nearby can help, but you also need to know how it works. Following our Guide, you will find all the necessary information for a great purchase.

Why is it important to have a breathalyzer?

Since you plan to buy a breathalyzer, it’s important to know how it works, isn’t it? After all, the blowing procedure is only part of the process.

There are several types of breathalyzer, but all follow a rule: they are based on the chemical reaction of an agent, exposed to ethyl alcohol. That’s where the technical name of the equipment comes from: alcohol meter.

Due to Federal Law 11.705 / 08 (Dry Law), the driver caught with any amount other than 0.00 milligrams of alcohol per blister air is liable to a fine and suspension of the right to drive.

So the importance of having equipment capable of helping you to understand your condition. Studies indicate that each dose of alcohol ingested takes approximately 1 hour to dilute in the bloodstream.

And this complicates a little more, because the drinks have different alcohol content. Not to mention that no one person is the same in terms of size, weight and metabolism.

How does the breathalyzer work?

The breathalyzer works by blowing. The air flow generated goes into the device, where there is a chemical agent, which will react if exposed to ethyl alcohol.

The equipment needs more than a liter of air to perform the measurement, equivalent to at least five seconds of exhaled air. So, prepare the lungs.

In the device, the “amount of” reaction is measured by circuits and sensors, which present it in milligrams of alcohol per liter of air. The chemical process eliminates all alcohol received, and is now ready for the next blower.

Having alcohol in the lungs happens because our body absorbs part of everything we eat (digestive process). And this absorption takes the content into the bloodstream, including alcohol in what we eat and drink.

The lung does an air filtration process, where it delivers oxygen directly into the bloodstream, and takes out carbon dioxide. If there is alcohol in the bloodstream, the lung will end up “exhaling” part of it along with carbon dioxide.

And that is why the breathalyzer works as a device for indicating and measuring alcohol content.

What types of breathalyzer are there?

As a rule, every breathalyzer works from a chemical reaction. From the most portable ones that are carried in cases, any search will lead you to different types.

Regardless of what you intend to purchase, you must take into account the reliability of the equipment. After all, Contran determines that the equipment is approved by INMETRO, meeting the requirements of the agency regarding precision and quality.

Thinking about the breathalyzer models, we can have it of two most common types: disposable or by fuel cell.

    • Disposable : They are single-use equipment, where the air is inflated in bags for this purpose, which, after being filled, are placed in a test tube with reagent. When emptying the air, placing the tube at the outlet of the bag, the reagent changes color, indicating the presence of alcohol.
    • By fuel cell : It is the most used by the Brazilian police. The breath containing ethyl alcohol generates a chemical reaction with the compound inside the equipment. The result is an electrical discharge and water in the form of steam. The equipment has sensors to measure the intensity of the discharge, which is presented in g / L of alveolar air.

 

What can be accused on the breathalyzer?

It is not just alcoholic beverages that have ethyl alcohol in their composition. Some medications, especially herbal medicines, also have it, as well as mouthwashes.

The truth is that certain foods, soon after ingested, undergo fermentation in the stomach, also releasing a small amount of alcohol.

And as the Prohibition Law determines zero tolerance, you may not even go to prison for low graduation, since the Law determines imprisonment from 0.33 mg / L, but will suffer the penalty of almost R $ 3,000.

Science explains that in these cases the alcohol will disappear in minutes, not being a concern. But if you ingest and drive, and are stopped in a blitz, try to explain the situation and wait a few minutes before the test.

Or – and most recommended – go to a laboratory (or emergency room) and request a blood test to check the alcohol content.

A blood test done up to a few hours later, beats the breathalyzer test, and you can use it as a check to avoid being fined. Nor have suspended the right to drive.

After all, the goal is to know if you have alcohol in your blood, not your breath. The breathalyzer came to simplify that.

Is there a tolerance for the breathalyzer?

Legally speaking, there is. Metrological legislation (for equipment calibration) allows for a margin of error called “maximum permissible error”.

Provided for in Contran Resolution 432/13, it informs that only results equal to or greater than 0.05 mg / L are considered to verify the infraction.

How much?

Breathalyzers are really cheap to buy. And even more so when you compare your price with the fine you could take.

It is important to take into account, however, that household equipment may not be as accurate as that of the police. Pocket options are found starting at R $ 50. Some even have those rings for placement on the key ring.

If you want something that really works, be prepared to shell out a few hundred reais. Not to mention the periodic calibrations that the manual will inform you of.

Where to buy?

Finding breathalyzers for sale is not that difficult. With Prohibition and the use of equipment to verify the drunkenness of the driver, they ended up becoming popular. For this reason, you will find the equipment in major department stores.

An interesting option, in this case, is the use of the internet to search for online stores, such as Amazon. Featuring some good models, it will allow you to compare products, in addition to delivering your choice at home.

 

Purchasing criteria: What to watch for when purchasing a breathalyzer

At this point, you can already consider yourself an expert on the subject. However, if you are really thinking about purchasing the equipment, you should pay attention to some features. When researching the breathalyzer, focus on:

  • Calibration
  • Display
  • Portability
  • Type

Understand each of these factors below to make the best choice.

Calibration

This is, without a doubt, the most essential part of the equipment. Prefer the purchase of breathalyzers approved by INMETRO (they come with a seal). This condition guarantees the equipment tested in calibration and quality.

It is important to remember that the calibration of any measuring equipment must be periodic, as stated in its manual.

There are many options on the market without the approval of INMETRO, but which have also been calibrated by other agencies. Usually cheaper, they end up being the most common acquisition.

In this case, the advice is to perform the test several times over a long period of time, ensuring that 0.00 is really 0.00.

Display

Extremely useful for measurement, there are several devices on the market with the option of an LCD screen. There are also those whose equipment comes with three different lights, and those that simply change color.

Defining how it is interesting for you that the equipment works is a priority, as you will need to understand and deal with the measurement.

Although those with an LCD display are more practical, equipment with a color change due to the chemical reaction tends to be more accurate, because if there is alcohol there will be a reaction.

Portability

If you intend to purchase a breathalyzer, you must take into account its dimensions, and the accessories necessary for its operation.

Some models require the use of cigarette holders or straws, which must be transported together. Others need a refill after use.

Define the level of portability you want to have, and work from there. The most common is to find breathalyzers on drivers’ keychains.

Type

Something we have already covered in the article, it is also important to define the type of breathalyzer you want to purchase.

Do you want something for single use due to a specific event or situation? Or equipment with a refill for a few uses? Or else, a breathalyzer for various uses, because you intend to go out and ask your friends for a breath to buy alcohol?

For the most diverse uses, define well the reasons for its acquisition, and from there look for the most suitable models.
