An alcohol meter is a device that estimates the average alcohol content in the bloodstream with the ratio of alcohol to breast. Alcohol detection is important for preventing many traffic accidents or for detecting criminals. The alcohol meters that make this determination are of great importance for this reason.
It is prohibited to consume too much alcohol in legally defined amounts in traffic. It is necessary to drill blood and urine in order to detect alcohol areas above the limit by piercing this law. However, it is important to get this test result in a short time. For this reason, alcohol meters have been developed to detect the amount of alcohol in a very short time. In order to get the most efficient result from the device, it is necessary to breathe from the diaphragm, that is, the umbilicus. We will refer to the relationship between breathing a diaphragm and an alcohol meter; But first we get to know the device a bit.
What is Alkolmetren's Working Principle?
The unit of measure that indicates the amount of alcohol in the vicinity is called "promil". The gauge calculates the average blood value in the body with the ratio of the alcohol to the breath, and gives the amount of alcohol in the blood as promil with the closest value. For this reason, even the wet wipes with alcohol, which we have removed from our cologne or mouth, can affect the amount of alcohol that appears on the device.
Device; Light source, potassium dichromate solution, filter, photocell detector, measurement unit and indicator. Alcohol meters are defined as the chemical-based "redox reaction". The air supplied by the breath is drawn into the alkaline solvent when it comes into contact with the acidic potassium dichromate solution. Alcohol or ethanol in the air blown into the device is converted to acetic acid. The ethanol is then oxidized with acetic acid and the chromium in the orange-yellow dichromate ion is reduced to the green chromium ion. Likewise, the level of alcohol is measured by measuring the degree of color change.
Another type of alcohol-methylene working principle is as follows; When the alcohol meter blows the breath, the electric current passing through the electric circuits in the device changes according to the amount of alcohol. This current is measured according to the algorithms of the device and the approximate amount of alcohol is detected.
There are three types of alkometers. These; Breath meter, poison meter and alkoscope.
Breath meter; The chemical reaction mentioned above makes a measurement based on the resulting color change. Poison meter; Infrared optical and phonetic analysis, ie spectroscopy. It is Alkosens; In other words, the alcohol sensor detects the amount of alcohol in the chemical reaction in a fuel cell detectors.
Breathing Alcohol Meter and Diaphragm
We talked about the importance of breathing through the diaphragm in order to get an efficient result with alcohol. A diaphragm, a three-hole food conduit, a cork that opens into the aorta and the main vein. Stretch as you breathe. The diaphragm shaker helps to fully utilize the human breathing capacity, and breathing through this muscle is one of the right breathing methods. When people are born, they begin to breathe through the diaphragm, and over time, they abandon these habits. People usually breathe through the secondary muscles of the chin, neck and back muscles. This method is defined as restricted breathing and is called chest breathing. Full breathing does not occur with this method. It is necessary to use the stem to breathe through the diaphragm. Of course, it may be necessary to develop some tactics to adapt this breathing method to your life.
With this detail, we have realized the importance of diaphragm to obtain healthy and productive results from alcohol. Sometimes you'll see the news on TV. Drivers who use an alcoholic vehicle have difficulty breathing or briefly blow off the alcohol meter that the police have stretched. Sometimes they deliberately try to mislead the driver cops who do not breathe through the diaphragm. Because when the breathing is made through the diaphragm in the triangle of the food tube, the aorta and the main vein, the device will be given more alcohol. The cops insist on the alcoholic driver as "good blow". In fact, the expansion of this means "blow from the diaphragm". In this way, it may be possible to measure the amount of alcohol present at the nearest value as promil.
How was the alcohol meter invented?
Let's go to 1769 to evaluate the process of inventing alcohol. During this test, a car wall was hit by a steam powered car in France. Years later, in 1897, a taxi driver drank alcohol and hit a building. Alcohol is the first traffic accident with this effect. Over time, traffic accidents have increased with increasing number of vehicles and people, accidents coming to the end of the use of alcoholic vehicles have also become serious problems.
Significant links between the use of alcoholic beverages and traffic accidents occurred. In time-tested tests, an increase in the amount of 20 mgDL in the amount of alcohol in the blood was found to double the risk of death from traffic accidents. It was determined that this amount could reach up to 600 times when it reached 150 mgdl or more. Several studies have shown that alcohol drivers are 50 percent or more more likely to have an accident than others. All these efforts forced authorities to take some precautions.
In 1874, researcher Francis Edmund Anstie investigated the detection of alcohol in the breathing air by breathing a small amount of alcohol; Some of the urine was removed from the body was determined. The emergence of alcohol meters goes as far as the outcome of this detection. Work carried out in the following years came to a point and in 1927, W.D. Mc Nally has developed a device called "alcohol-based". Mc Nally, he invented the device to collect respiratory air, a pinch; With the color change there, he can determine if the person is drinking alcohol and that the police can detect if a driver has been drinking alcohol thanks to this device.
In the same year, Dr. Police Gorsky wanted to be swollen with a soccer ball from an accused for alcohol measurement. In the tests, 1.5 milligrams of alcohol was detected in 2 liters of breathing, which indicates that 50 percent of alcohol is alcoholic. In 1931, the biochemist Dr. Rolla N. Harger developed a device called 'drunkometer', which was a "drunk meter" for Turkish. In 1938, Indian police officers tested this device and received positive results.
This device was developed and the device called "Intoximeter" and "Alkometer" was invented in 1941. In 1954, Robert F. Borkenstein has invented a device called "Breathanalyzer" that takes up less space, is easy to transport and produces more efficient results. In 1958, this device began to manufacture and use the Indian Police.
NJ Stephenson Corporation, which developed this device, continued to market the "Alcolmeter" device that it developed in 1974. Since then, it has been used intensely by the police. In our country, the alcohol meter, which has become widespread in the 1990s, has started to be used by government institutions with various versions.
What is Alcohol Limit?
In our country, the alcohol limit for traffic is 0,50, which equals one gram of calories and half a gram of alcohol. It is prohibited to drive with alcohol above this limit. This limit is the beginning of relaxation, decreased attention, co-ordination and reasoning disorder. As this limit is exceeded, the effect of alcohol on people becomes apparent. Three promyl alcohol
