How Does Digital Breath Alcohol Tester shows result?

How to use the most accurate alcohol meter

How to use a digital breath alcohol tester? It is carried out according to the following basic steps:

Step 1: Start the machine

To start the device, first, you install the battery for the device (some devices also support a charging cord when needed). Then, hold down the power button or the Enter key on the body. The display shows the time to wait for the meter to start up; it will take a few seconds, when the meter beeps “pip” the meter is ready to measure the concentration.

Step 2: Insert the breathing tube into the machine

Depending on the design of the digital breath alcohol tester, the position of the breathing tube may be different (it can be on the side of the machine or in front of the screen...). When installing should screw the hose tightly and securely to ensure that breath does not escape.

Step 3: Measure the alcohol concentration

Blow into the tip of the breathing tube long enough and wait for a few seconds for the machine to analyze the data and display the results on the screen. Results response time ranges from 5 to 30 seconds and displays in alphanumeric or written form depending on the device type.

Step 4: Print parameters and results (for some models that support printing results)

In case you want to print the measurement results, you continue to select the Enter key on the body. The “Print” option will appear on the screen. If you want to print, select Enter. The printer will proceed to print a notice showing the results of your recent measurement.

Note: when using a digital breath alcohol tester

In order to effectively use the breath alcohol meter, and contribute to complying with traffic laws, you should note the following when using the device:

It is recommended to check the alcohol concentration in your breath before participating in traffic or after drinking alcohol for a few minutes to have the best treatment. If you have decided to drink alcohol, the safest way is still to use taxi or Grab services when leaving.

However, if possible, we advise against drinking while driving.

Digital breath alcohol tester: Precautions

In case you do not drink alcohol but only eat and drink foods containing alcohol such as fruit, soda, etc., to check the alcohol concentration. It is best to wait 15-30 minutes for the alcohol concentration to evaporate completely then measure again with the machine.

During use, you should pay attention to store the device in a dry place, do not leave the device in a humid environment. Ideally, you should store the device in the box when you buy it and keep it in a dry place.

Regularly check the battery and replace it on time

Ideally, for the machine to work correctly, you should check the machine once every 3 months.

The last thing we want to advise you is to be careful when choosing to buy digital breath alcohol tester. You should choose addresses and facilities that ensure prestige and quality, as well as carefully check the equipment before buying and requesting a reasonable warranty.

Alcohol testers are very popular in the beverage industry, fruit processing, beer, and in traffic around the world.

Recently, in Vietnam, contrary to the previously bleak atmosphere, the alcohol meter market has become hotter and has become a big focus. Alcohol meter is an indispensable equipment of the current traffic police

Structure and working principle of alcohol meter

The structure of the digital breath alcohol tester is quite simple, including:

• 01 chamber contains liquid with a certain boiling point.
• vessel to condense steam, in order to maintain the initial temperature of the liquid to test.
• Standard thermometer 0.02 degrees Celsius, between 95 and 115 degrees Celsius.
• The heat source is the dune temple.
• The outlet is used to remove the cleaning or test liquid from the tank.
• measured cylinder
• A set of dedicated alcohol meter is quite full of accompanying tools
• A set of dedicated alcohol meter is quite full of accompanying tools

 

Working principle of digital breath alcohol tester

In chemistry, alcohol has the formula C2H5OH. In the alcohol meter, there is chromium (VI) oxide CrO3. When these two substances meet, they will create a blue-black compound, because CrO3 reduces to Cr2O3.

Based on this, the traffic police will use a tool containing CrO3 to analyze the alcohol in the driver's breath.

If the driver of the car breathes with alcohol vapor, the color in the concentration meter will turn blue-black. And based on color variation analysis, the meter will tell the police how heavy or light the drinker is.

Is the alcohol meter accurate?

Perhaps this is the question and concern of many people? Or do some people wonder if it is possible to bypass the digital breath alcohol tester?

First of all, according to our understanding, there are currently 3 methods of determining blood alcohol concentration, including:

• Blow into an alcohol meter based on color change in a chemical reaction involving alcohol.
• Infrared technique is used to measure the spectrum of the breath; the percentage of alcohol present in the breath will give different colors.
• Applying the fuel cell principle, the machine will detect whether or not acetic acid, electrons and protons in the breath from the chemical reaction. Based on this to conclude the amount of alcohol in the blood.

Thus, with 3 methods of determining the blood concentration in the blood through the breath, it will give us the necessary information.

Which method is more feasible?

Moreover, the method of measuring the alcohol concentration in the breath with digital breath alcohol tester is more feasible than the way to find the concentration of alcohol in the blood by taking blood or urine for testing.

When you drink alcohol, beer, they will go to the stomach, intestines and blood to be absorbed. Alcohol has the property of not breaking down when absorbed and chemically altered in the blood.

When blood passes through the lungs, part of the alcohol penetrates the membrane of the air sac, it is volatile, and so it will be mixed into the air of the air sac.

Therefore, it is possible to determine the gong present in the breath of the drinker. And using an alcohol meter will give us accurate and fast results.
