Motorists will have to choose between the chemical breathalyzer and the electronic breathalyzer. First of all, we would like to point out that the chemical model is for single use only. You must therefore throw it away after using it. As for the electronic breathalyzer, it can be reused several times and is very fast. One thing is certain: these two types of breathalyzers are equally accurate. You are free to choose the one that best meets your expectations.
The best breathalyzers on the market are those certified by the NF X 20 704 standard. This identification clearly attests that the device complies with all safety requirements. This standard therefore testifies to the proper functioning, quality and legal compliance of the device. By choosing an NF certified product, you are assured of using a breathalyzer that has undergone thorough testing from an approved certifier.
The best breathalyzers come with a set of accessories, including a protective cover, replacement mouthpieces, batteries, a rechargeable battery, a charger, a USB cable and even a cigarette lighter adapter. Some come with an automatic function and a memory function for the tests performed.
As the breathalyzers on the market each have their own specificities, the time at which the results are displayed varies greatly. For high-end products, it takes less than a minute to perform the test. On entry-level products, the results are displayed only after two or three minutes.
The breathalyzer should be neither too big nor too small to avoid wasting time looking for it in case of a road check by the police. Even if you choose a disposable model that comes in a soft plastic container, make sure it is always handy and prominently displayed in the glove compartment.
Drunk driving is the main cause of traffic accidents, not only in the UK, but anywhere in the world. To make motorists more responsible, they must have a functional breathalyzer in their car.
Thus, after having had a few drinks, a driver must check his alcohol level or that of his friend. If the authorized blood alcohol level is exceeded, measures must be taken. It is not difficult to read the results of a breathalyzer.
For the chemical breathalyzer
If you are using a chemical breathalyzer, you must break the ends of the plastic tube before using it. You must take a deep breath and blow to inflate the balloon in one exhale. Then deflate the balloon so that the contents can pass through the chemical reagent in the mouthpiece. If the yellow crystals in the tube do not change color, the test is considered negative. Alternatively, if the crystals turn green, it is more responsible to leave the wheel to someone else.
For the electronic breathalyzer
The electronic breathalyzer works in much the same way as the chemical model. You place a disposable mouthpiece on the device and blow into it until the device emits an audible or visual signal. The alcohol level will then be displayed on the screen. If it is higher than 0.5 g/L (or 0.25 mg of alcohol per liter of exhaled air), it would be more prudent to take a cab home.
As we keep saying, the majority of fatal accidents are due to drunk driving. Note that the body needs one hour to eliminate the equivalent of one glass of alcohol in the blood. If you drink a lot of alcohol, the chances are high that you will exceed the legal blood alcohol level. At 0.5 g/L, alertness decreases, the visual field narrows, distance perception is blurred and reaction time increases. According to the authorities and health specialists, a motorist should never consume more than 2 glasses of alcohol.
Also known as a balloon breathalyzer, this device consists of a solid chemical reagent (potassium dichromate) in the form of crystals that change color upon contact with ethanol molecules.
Advantages:
- This device is inexpensive
- The results are very fast
Disadvantages:
- It is a single use device
- The shelf life is approximately 2 years
- It does not quantify the precise blood alcohol level
This device uses an oxide sensor to measure the reactivity between the metal oxide and the alcohol molecules in the exhaled air. Thus, when the alcohol molecules come into contact with the metal oxide, the conductivity changes according to the concentration of the gas detected in the breath.
Advantages:
- This device is compact.
- It presents excellent performances for low concentrations
- Its power consumption is low.
Disadvantages:
- This device performs poorly if the human breath flow is low.
- High temperature and humidity can affect the performance of the sensor.
- The risks of false positive, because the device does not detect the residual alcohol present in the mouth.
Contrary to the other two types of breathalyzers, the present model is equipped with an infrared spectroscopy which is the technology having the same legal metrology as a blood test.
Advantages :
- Its effectiveness is indisputable.
- It is the only device capable of detecting residual alcohol in the mouth, trachea and esophagus.
- The longevity of the sensor is almost infinite.
Disadvantages:
- The cost of the sensor is expensive due to its advanced technology.
A breathalyzer is completely different from a breathalyzer. While the former is an over-the-counter device intended for motorists and certain employers, the latter is the accessory used by law enforcement agencies to check the blood alcohol level of people suspected of driving while intoxicated.
Whether chemical or electronic, the breathalyzer is a mobile device that allows you to check the level of alcohol in your breath. When in doubt, a motorist or a motorcyclist must perform a breathalyzer test. It is a responsible gesture intended to ensure his safety and that of the other users of the road.
The alcohol ignition interlock device or EAD is an on-board electronic device that prevents the car from starting if the alcohol level measured in the breath is above the authorized threshold. Technologically advanced, the alcohol ignition interlock is one with the car.
The use of an alcohol ignition interlock device is often the result of a decision by the prefect. It is an alternative to license suspension. So, if you have not yet violated the rules of driving with a higher alcohol level in your blood, just make sure you have a breathalyzer in your car.
One drink is fine, but three drinks can cause damage! This adage is still true today since the share of alcohol in fatal accidents has not changed despite decades of prevention. Basically, the reasons to buy a breathalyzer revolve around this subject.
It is an essential safety accessory
All French motorists are no longer required to have a working chemical or electronic breathalyzer in their car since 2020. However, always have one for your safety and that of your family. You will know that this accessory is very useful, especially after a drunken night with friends.
It's for your well-being and that of others
For safety reasons, it is wise to have a breathalyzer in your car. In the spirit of clarity, this device will prevent you from risking your life by getting behind the wheel when you shouldn't. If the indicators show that your blood alcohol level is above the legal limit, don't drive. Instead, take a cab or get a ride home.
A friend may need one
A breathalyzer is still useful even if you haven't had a drop of alcohol. The device could be useful for the friend who has had too much to drink and can't remember where they put theirs. If your friend doesn't pass the test, it is your duty to refuse him or her the wheel. Always be rational, especially since alcohol causes thousands of deaths each year.
To drive with peace of mind
Implicitly, the presence of a breathalyzer in your car will remind you of your responsibility towards others. You'll be able to drive with peace of mind because you're fairly alert, even after you've had a drink. If you feel any effect, take out your breathalyzer and use it.
You will understand your body better
Using a breathalyzer will give you a better understanding of your body. You will know how your body reacts after having 1, 2 or 3 drinks. From now on, you will know what to expect.
In our opinion, the best brands of breathalyzers in 2022 are :
BLO UK is an English manufacturer specialized exclusively in breathalyzers. Although it is still little known, this brand offers NF certified products that will be useful in your daily life.
VicTsing is a brand expert in creating high-tech devices useful in everyday life. Its range of breathalyzers is especially known for their performance and practicality.
Topelek is a key player in the solar lamps and computer accessories sector. With a strong know-how, the brand also offers practical and very reliable breathalyzers.
Specialized in road safety accessories, Patuoxun offers a rich range of breathalyzers that seduce by their ergonomics, but also by their design.
Norauto is a French automotive service center whose origins date back to 1970. Taking advantage of this long experience, the company started offering safety accessories, including chemical and electronic breathalyzers.
The diagram below will help you to get an idea of the typical prices for each price range (entry-level, mid-range and high-end).
However, more expensive does not necessarily mean better.
We therefore advise you to always consult our ranking before deciding, rather than blindly relying on price ranges.
Check the expiration date
If you plan to buy a single-use breathalyzer, remember to check its expiration date, but also if it is NF certified. This way, you will be sure to use a quality product for at least 24 months. If you have any concerns, switch to another model.
Prepare the tube properly
When using a chemical breathalyzer, be sure to break off the plastic tips so that you can blow air into the device. Normally, the kits are easy to break off. All you have to do is apply a little pressure to both ends and you're done.
Pull the white crystals
To avoid repeating the process, remove the white crystals that are in the tube. These substances are only there to preserve the product. However, this operation is useless if you have to blow directly into the device, as is the case with the electronic breathalyzer.
Take a deep breath
Fill your lungs with air before blowing into the device. This will allow the balloon to inflate properly. When it's full, close the valve and gradually empty the container. The goal is to get the air into the crystal tube or sensor to find out the alcohol level.
Have 2 breathalyzers in the car
For single-use breathalyzers, it's a good idea to have several in your car. If you screw up the first test, you can always make up for it with another one. This is also very useful if you have been drinking with a lot of people. The person with the lowest alcohol content will be responsible for driving the others home.
Whether it is chemical or electronic, a breathalyzer always works the same way. After blowing into the device, a driver is informed of the amount of alcohol in his or her blood. If the level is higher than 0.50 g/L, he or she is strictly forbidden to drive, at the risk of being arrested.
For the chemical test, the test is negative in case the crystals do not change color. If they turn green, it means that you have exceeded the authorized threshold. The electronic test is easier to interpret and simply shows you the level of alcohol in your blood.
Thebreathalyzer is the detection device used by law enforcement to confirm the level of alcohol in your blood. It is therefore an authorized device in a legal proceeding, which is not the case with the breathalyzer, which is a free product for sale.
From 2013 to 2020, thebreathalyzer was a mandatory accessory in the car although its absence did not always result in a fine. Despite this, many organizations encourage motorists to have one in the glove compartment. It is a way to make them aware of the dangers of drinking and driving.
