As we know from history, all attempts to uproot the love of alcohol in the minds of our compatriots ended in complete failure. Most Russian people do not imagine their life without periodic hot doping, and even if the holiday is outlined. ..
But alcohol not only adversely affects your health. Blurring the consciousness of a person, it becomes the cause of accidents and injuries, which often end in the most terrible consequences. For this reason, it is very important in our country to control the level of alcohol in the blood of a person. For this purpose, a special device has been created - an alkotester. In this article, we'll talk about how to choose it.
How does the breathalyzer work?
Getting into the human body, alcohol almost immediately spreads throughout the circulatory system. As a result of gas exchange occurring in the lungs, some of it in the form of vapors is removed from the human body with exhalation. The principle of the breathalyzer is to analyze the composition of the exhaled air. This analysis can be performed in several ways, as will be discussed below.
Who needs a breathalyzer?
Many of us think that an alcohol test is needed solely for traffic police, who identify with it the unconscious drivers who abuse alcohol before the trip. In fact, the meter can also come in handy:
To the driver
If before you get behind the wheel, you could not resist and still sipped from a glass or a glass, then you need a check on the alkotester first of all. Studies have shown that when the driver's alcohol content in the blood exceeds 0.3 ppm, the risk of a road traffic accident increases several times. Therefore, to make sure before the trip that you have not exceeded the permissible limit is practically a vital necessity.
Parents of
Despite all attempts to legislatively restrict the sale of alcoholic beverages to minors, it is easy to purchase alcohol in our country. Find out for sure whether your son or daughter drinks alcohol-containing drinks, and in time to take adequate measures will help the breathalyzer.
The head of the company
The habit of "charging" in the morning is quite common in our society. If you hold a management position, then no one else will be interested in the sober state of your subordinates. It's not just about the performance and quality of performing professional duties.
A worker who has drunk before workday can provoke a serious accident, cause serious injury to himself or colleagues and even cause a fatal accident. To prevent the occurrence of such situations in the workplace will help check the personnel on the breathalyzer at the beginning of the work shift.
And of course, the breathalyzer is necessary for doctors of narcological clinics and dispensaries.
Algorithm for selection of Breathalyzer
Step 1: Accuracy of
The accuracy of the Breathalyzer depends primarily on the type of sensor used to analyze the composition of air. There are three types of such sensors:
- electrochemical;
- semiconductor;
- photometric.
The best breathalyzer is electrochemical. Like photometric, it gives the minimum possible error to date, but it serves longer and is very unpretentious in operation. Instruments with semiconductor sensors have less measurement accuracy, but are more affordable.
So, a simple breathalyzer on semiconductors can be bought for 2-2,5 thousand rubles. Such devices are most often purchased for home use, children's control and similar tasks. The electrochemical or photochemical alkotester can "pull" up to ten thousand. And we are talking here about personal models, a professional device will cost much more.
Step 2: allowable load on the sensor
In the simplest and, therefore, inexpensive models, the sensors are designed for several tests per day. In professional devices intended for doctors or road patrol services, the sensor can be used without restrictions.
To understand how much "hardy" sensor you need, clearly define the range of tasks for the purchased alkotester. If it will be used in everyday life - enough and five measurements a day. Do you drive a car? Buy the device with a calculation of 7-10 measurements per day. For use in an enterprise or in a medical institution, it is necessary to take a model with the maximum sensor resource.
Step 3: units and range
When measuring blood alcohol level, the following units can be used:
- mg / l;
- ppm;
- percent;
- BAC.
We believe the most expedient is the purchase of a device that displays the measurement results in ppm. This is due to the fact that the maximum permissible levels of alcohol in the Laws and other regulatory acts are specified precisely in such units of measurement.
For a household breathalyzer, a range of 0 to 3.5 ppm is sufficient. It is 3.5 ppm is considered a lethal dose for the average person. Professional devices should have a slightly larger range - from 0 to 5 ppm.
Step 4: Do I need a contact?
Breathalyzers are contact and non-contact. The first are equipped with a mouthpiece into which the test person must blow. The readings of such devices are more accurate, and in the open air they are simply irreplaceable.
Step 5: choose the manufacturer
If you are looking for an inexpensive personal alcohol meter - pay attention to the products "DA5000" or "Business".These devices have a semiconductor sensor, but for home use their accuracy is quite acceptable.
For group testing it is better to buy a breathalyzer with a higher accuracy. It can be "AKPE-01M" or "Expert-2009".
Now you know what an alkotester is, and how to choose it. We hope, that your new assistant will help to avoid unpleasant consequences of alcoholic intoxication.
