Guide to buying breathalyzers
Although we have not yet reached the level of France, where it is mandatory to carry a breathalyzer in the car, the truth is that carrying one of these devices in our vehicle is not a bad idea. Not only because of the fine, which depends on whether we find controls or not, but because a high level of alcohol at the wheel is a serious risk of an accident. Something that you can avoid if you follow the advice in our guide to buying the best breathalyzer and get one of these devices.
Shopping guide
Professional or “domestic”
The first question that always arises when buying a breathalyzer is whether to opt for a professional model or a home one. There are many comments that indicate the “reduced precision” of these second models, although the truth is that in our market analysis we have found viable options at reasonable prices.
Anyway, the answer depends on our use and specific need. If what we need is to measure our blood alcohol level in a timely manner after a night of drinking, any model will surely serve us, even a disposable one. But if these measurements must be made very frequently and require high precision, then the idea of getting a higher quality model seems viable.
An issue that is also influenced by cost, since professional models rarely go below 100 euros, while we can find simple breathalyzers from approximately 15 or 20 euros.
Homologation and precision
In line with what we have stated above, there are two elements that can be useful when reviewing any comparison of breathalyzers that we have at hand. We talk about the homologation and the precision of the device. Starting with the homologation, this certifies us that the product has gone through a verification process, which adds an extra quality to the device. However, there is always the question of whether the homologation is real or simply an invention of the manufacturer.
Where there is less deception, although there is also it, is in the precision. This precision indicates the margin of error that the device has in each measurement. The smaller this margin of error, the greater the accuracy of the device. So it is convenient to look for products with reduced margins that are not greater than 0.02 milligrams per liter or 5% of the measurement. Higher levels can end up being a source of problems when interpreting the results.
Battery
The process of measuring alcohol in blood requires energy. An energy that, depending on whether we are talking about a cheap breathalyzer or a somewhat more expensive model, will have a different origin.
In the case of cheap breathalyzers, it is common for that energy to come from two or three AAA batteries, which we will have to change as they run out. The other, somewhat more advanced, option is for the breathalyzer to have a USB-type battery, which requires only one such cable to charge it.
In both cases, it is essential that we always have a clear idea of the battery level that the device has left, which is usually shown on the screen. Especially if we take into account that most breathalyzers on the market have a bad habit of losing accuracy as they run out of battery.
Maintenance
As a last aspect, it is essential to talk about the maintenance of the product we have chosen. An aspect that we must consider in all cases, but especially if we plan to use the product intensively.
This leads us to evaluate the nozzles used by the product. The ideal would be to use a nozzle in each test and discard it, but if it is for domestic use, the truth is that we can wash them with soap and water and discard them only when they are very damaged. However, be sure to check if the product can use universal nozzles, as well as their price.
The other maintenance cost has to do with calibration. A process that is usually quite expensive and that must be executed every certain number of measurements. In the case of cheaper models, it is usually cheaper to buy a new device than to send it to be calibrated, but if we have opted for an expensive model, it is something that we must consider, regarding how much it costs to update that breathalyzer.
Frequently asked questions
Q1: How to calibrate breathalyzer?
The calibration process of a breathalyzer is carried out in a specialized laboratory, in which the device is connected to a system that generates air samples with a certain level of alcohol in them. During this calibration process, it is verified that the breathalyzer is capable of accurately measuring the given samples. If the calibration process is positive, the product can be returned to service, while if it is not, it will need to be repaired by a specialized professional.
Q2: How to make homemade breathalyzer?
To make this homemade breathalyzer, we will use an MQ sensor, the one used to measure the level of alcohol in blood, together with a circuit board with 10 sockets for LEDs and the rest of the corresponding circuitry elements, as well as the corresponding LEDs that will measure the blood level and they will inform us more clearly. All this without forgetting the source, as well as the corresponding power supply. All these elements must be connected correctly to execute the aforementioned blood alcohol measurements. In any case, there are more detailed processes of this assembly on the net.
Q3: Which is better, a breathalyzer or breathalyzer?
Although technically the same, there are differences between a breathalyzer and a breathalyser. Generally, the breathalyzer is a portable device that we can take anywhere and use it comfortably to measure the breathalyzer. On the other hand, the breathalyzer is usually fixed, mounted on a police van, is much more expensive and, at least, much more accurate than the breathalyzer. In addition, the breathalyzer usually includes memory and a printer, to give legal character to the tests carried out. That yes, it is obvious that except for the police forces, nobody will buy one of these models given the high price and the “little operational” for specific measurements.
Q4: How is an approved breathalyzer different?
As with other products, the approved breathalyzer is one that has gone through a laboratory procedure in which the product has been tested with samples whose concentration is already known. In the event that the breathalyzer is capable of accurately measuring such samples, it receives the corresponding homologation, which ultimately assures us that we have a product whose measurements are precise or, at least, correct.
Q5: Is it mandatory to have a breathalyzer in the car?
In Spain it is not yet mandatory to carry one of these devices in the car. But if you drive through France, you must carry a disposable breathalyzer in your vehicle, just as you wear the reflective vest. A measure that comes and goes in the neighboring country and that the DGT has been studying for years for Spain, although without making a decision on the matter. Anyway, the arrival of vehicles with built-in breathalyzers seems to be close, so you don’t have to think too much about it anyway.
Q6: Is it safe to use a throwaway breathalyzer?
Like everything, it depends on the manufacturing quality of the device. However, throwaway products do not contain electronics, but instead contain a chemical compound that reacts to alcohol in the air, in an approach similar to the drug tests we see on customs TV shows. In any case, it is advisable to verify if the product is approved and has a reduced margin of error, since these two elements are evidence of a more efficient system when it comes to measuring our alcohol level.
Q7: How to make a breathalyzer with arduino?
The process of making a breathalyzer with arduino is quite simple, since it follows the same process as the creation of other similar devices. In this case, the secret is in the sensor, which must be able to read these concentrations of alcohol in the air. The rest of the scheme does not require more than a battery, which powers the device, as well as an LCD screen, in which to see the results of the measurements that we carry out.
Q8: How do you read a BAC breathalyzer?
In truth, the BAC breathalyzer is no different than any other that we have at our fingertips. The difference lies in the measurement. BAC stands for Breath Alcohol Content or breath alcohol content, once translated. In practice, this measure is equivalent to the milligrams per liter that we have as a reference in Spain, with the exception that the BAC uses the liter of air as a base. So, a concentration of 0.05% BAC would be equivalent to 0.05 milligrams of alcohol per liter. In any case, almost all breathalyzers allow you to switch between units, so as not to get involved.
How to use a breathalyzer
Surely if you travel at night through areas with nightclubs and other entertainment venues, you will have already passed the occasional breathalyzer test. But if this has not been your case or you simply want to know how to use a breathalyzer, we give you a small guide on how to proceed and travel more safely when you drink a little, as long as you have one in the glove compartment.
Initializing the product
Practically all the breathalyzers that we have on the market need a short warm-up time, so that the measuring system reaches the necessary temperature to carry out said measurement. Depending on the model, this time usually ranges from about 5 to about 30 seconds. Once ready to start, the product will let us know directly on its screen and, depending on its approach, with an audible warning.
blowing
Since it is an air measurement process, it will be necessary to blow through the breathalyzer’s mouthpiece or air intake. It is important to maintain the airflow for as long as the device requires, which is usually 5 to 10 seconds. In general, the breathalyzer will notify us with a beep or alarm when it is no longer necessary to blow more. Some models keep a continuous beep while we blow, as proof that we are doing it correctly.
reading the result
While you catch your breath, it’s time to wait for the result to appear on the screen. Once the process is complete, you may get an alert if that measurement is above the level determined by the manufacturer or by ourselves, depending on the model. In any case, the alcohol level will be shown on the screen in the unit that we have chosen in a clear and visible way.
Interpreting the result
Leaving aside the alarms, with the result already seen, it is time to decide if we are in a position to drive or not. In general, the maximum limit of alcohol in the air in Spain is 0.25 milligrams for all drivers, although with some exceptions. One of them is that of novice drivers, with less than two years of license, which reduces the limit to 0.15 milligrams per liter of air. This rate also applies to professional drivers. If your alcohol level is higher than indicated, you should not drive. Although our advice is that, behind the wheel, 0 alcohol is always the best.
Maintenance
As a final point, we take a look at product maintenance, which should focus on two main elements. One of them is the battery. If you have a product that works with conventional batteries, you should change them when you see that the energy level on the screen is reduced. If it is a battery model, you will only have to connect the product to any USB charger, to recover the lost energy. It is important to remember that these models can lose efficiency with low power.
Regarding the nozzles, the other important aspect, it should be remembered that they can be washed with soap and water, discarding them only when they are very damaged. What is important is that, if you plan to do several tests at the same time, use different mouthpieces, to avoid cross-contamination of the tests.
