All you need to know about Breathalyzers.
According to Coherent Market Insights "The global breathalyzers market is estimated to account for US$ 6,384.5 Mn in terms of value in 2020 and is expected to reach US$ 71,866.2 Mn by the end of 2027".
We hear and read about drivers charged with drunken driving after being involved in an accident, and a news report on the accident will normally state what the driver's blood alcohol level was and what the legal limit for blood alcohol is. For example, if a driver's blood alcohol level is 0.15, the legal limit is 0.08. But what exactly do those numbers imply? And how can cops determine whether a driver they suspect of being inebriated is indeed inebriated? You've definitely heard of the Breathalyzers, but you might be wondering how a person's breath might indicate how much they've consumed.
Drunk drivers must be removed from the road for the sake of public safety. Alcohol was involved in around 38 percent of the 42,000 traffic deaths in the United States in 1999. Drivers who pass roadside sobriety tests — such as touching their noses or walking in a straight line — may nevertheless be over the legal blood alcohol limit and pose a risk on the road. As a result, police officers deploy cutting-edge technology to detect alcohol levels in suspected inebriated drivers and detain them.
To measure the blood alcohol concentration (BAC) in drunken-driving suspects, many field officers rely on breath alcohol testing instruments like Breathalyzers is one example. We'll look at the scientific ideas and technology behind these breath alcohol testing devices in this post.
Why Test?
The legal definition of intoxication is the blood alcohol concentration (BAC) level. For arresting drivers suspected of driving while intoxicated (DWI) or driving under the influence (DUI), obtaining a blood sample in the field for later laboratory examination is not practical or efficient (DUI). Urine alcohol tests were just as inconvenient in the field as blood sampling. A means to measure something relevant to BAC without penetrating a suspect's body was required.
