Breathalyzer Accuracy

Breathalyzers, also known as alcohol testers , are measuring instruments that measure the breath alcohol (breath alcohol content). In the lungs (in alveolar) blood and breath are separated by a thin, gas-permeable membrane. Only if one blows vigorously, and the sufficient amount of breath has been exhaled, will a measurement be taken. Breathalyzers on the market differ mainly in the use of different measurement sensors. There are semiconductor and fuel cells. Fuel cell breathalyzers must be sent back to the manufacturer to be recalibrated every 6- 12 months. However, Alcomate Company exclusively offers a pre-calibrated sensor that can be changed by the consumer whenever the need be.

The following factors must be taken into consideration in order to get an accurate alcohol measurement:

1) Gender

2) Age

3) body weight

4) alcohol consumption

5) diet on the day of alcohol measurement

6) Time

7) alcohol beverage of choice.

8-) Physical condition (disease, medication, drugs)

9) Mental Health (stress, fatigue)

On the subject of Breath Alcohol vs. Blood Alcohol Content:

Extensive test series have shown that the breath alcohol concentration (AAK) corresponds to about 1 / 2,000 of the blood alcohol concentration (BAC) in a blood sample taken at the same time. However, this ratio is not constant, but based on individual factors, particularly dependent on the respective body temperature. Also the time in which the alcohol passes from the gastrointestinal tract into the blood (absorption phase), to different degrees of alcohol concentrations in arterial and venous circulation also plays a factor. During this phase, which lasts up to 2 hours after drinking, the venous blood alcohol concentration may differ from the measured breath.

The effects of alcohol in the human body:

Transition of the alcohol in the body fluid (absorption): about 40-50% within 15 minutes and approximately 65% within 30 minutes. This means that if you take a drink and test with a breathalyzer thirty minutes after your last sip of alcohol you may still not be at your highest level. So in some cases people who have tested with a breathalyzer may think they are below the legal limit but then twenty minutes later when they get stopped by the police they test over the limit (0.08). If you rest for sixty to seventy minutes after drinking you will have reached your peak and probably be on your way down.

Eating can subdue alcohol content and cause it to enter your blood stream over an extended period of time. This will mean you will not feel the full impact of the alcohol as you would if you drank a large amount over a short period of time on an empty stomach.

Here is the approximate amount of alcohol that can be metabolized over time. It can be measured with a breathalyzer or by drawing a blood sample and having it sent to a testing facility.

Degradation rate: In women, about 0:08 to 0:10 per hour In men, approximately 0:10 to 0:15 per hour

As you can see women are affected more by alcohol and should be especially careful. Even one glass of wine in a woman weighing under one hundred pounds can create an impaired state. Just remember to be safe at all times. Do not drink and drive or let your friends drink and drive. It is not worth the risk! And as you may already know you can buy a breathalyzer on amazon because they have many models from which you can choose.
