Dangerous products for drivers. Test breathalyzer DrinkMate

The use of the products shown in the photo above significantly increases the probability of deprivation of rights. Who would like, eating a few sweets with liquor or rum, lose a driver's license? So, what could be so dangerous for drivers in products? Of course alcohol. It is clear that having drunk even a glass of alcohol, it is better not to get behind the wheel. What to do if you drank grape juice, kefir or kvass? Before you go somewhere by car, having eaten or having drunk something with the content of alcohol, you should check yourself without waiting for the cherished “blow in a straw”.

To be sure that there are no signs of alcohol in the blood - we will use a portable (even pocket) breathalyzer for the DrinkMate smartphone.



Otherwise, then you will have to prove that you ate a candy with rum, and did not drink a glass of vodka and drink beer.



I somehow had a noname breathalyzer in my car. His testimony was enough for exactly one time. And that's all. Then the breathalyzer refused to work and had to wait up to half an hour before he “sober up”.



Before you go somewhere, you need to know how food and liquid affect the concentration of alcohol in your blood. After all, even seemingly innocuous products showed frightening numbers. In Russia, there is a law under which the driver will be sober if the level of alcohol in his blood does not exceed 0.3 ppm = 0.03% YOU. Alcohol tester DrinkMate by default shows in “BAC” (blood alcohol concentration). Promille is one thousandth, 1–10 percent. For example, 50 mg% = 0.50 ppm = 0.05% BAC.

Few details about DrinkMate

Breathalyzer is in beautiful packaging. There is an instruction, a cover and the device itself. It is powered by a smartphone via USB. OTG (USB hosting) support by phone or tablet is required.



It looks like a cylinder about 5 cm high. Type of sensor based on semiconductors.



Reacts to ethanol vapor. Many complaints come to the address of devices of this type, they say, they show high concentrations of alcohol even in juice or kefir. Let's check.



Download the application DrinkMate IOS and Android . In my case, this is Android.



The application counts "BAC", but in the settings you can specify other units of measurement.



Statistics of measurements and registration of location on the map are kept.



How to measure? It's pretty simple. Insert the device into USB. Turn on the DrinkMate application and click “Check blood alcohol content.” The device is warming up at this time.



After we blow it as shown in the picture.



For test measurements, we need one drinking friend and a little patience. Measurements should not be made, one by one. The device must rest for at least a minute. He will inform you about cleaning the sensor with a special message.



The application has fun features. You can take a selfie photo and share it online. Sorry, I removed my address. Remained the inscription "street ...., Stavropol Territory, Russia."



But we came here not to get drunk, but to seriously test the operation of the device. Therefore, I will make selfie products.



The first test was conducted on traditional drinks - kvass, whiskey and beer. As a result, the breathalyzer showed: 0.5 kvass = 0.041% YOU, 1 glass of whiskey = 0.068% YOU, 1 can of beer = 0.037% YOU. Data as expected. It is noteworthy that after 20 minutes, the alcohol from the brew evaporated somewhere and the device showed zeroes.

And what if you eat candy? Yes, and with alcohol filling!



Especially for such a test, opened a set of alcoholic sweets.



Eat a slice of tequila. Measurement showed 0.059% YOU. Complicate the test. Many people use aerosols and medications containing ethanol. The device and here showed amazing numbers 0,039% BAC - aerosol from sore throat.



The most unusual measurement, alcohol showed up in a sausage sandwich. Breathalyzer happily reported that after consuming a single sandwich, the concentration was 0.036% BAC. Again, after 20 minutes, there was no trace left of the sandwich, candy or aerosol.



I was always interested in the question, why kefir can not drink while driving? There was even a story on TV, where one grandfather was deprived of rights due to the use of kefir. Well, OK.



Kefir is.



As a result, at 0.000% YOU. The same is observed in measurements with concentrated cherry juice and TAN fermented milk product. Drink kefir freely only if it is not fermented.

The old breathalyzer was silent throughout the test. But at the beginning, when measuring with beer, he showed the numbers that were the same with DrinkMate .
