Etymology
"Breathalyzer" is a portmanteau word combining the words "breath" and "analyzer".
Meaning
A breathalyzer is a device used to measure the alcohol content in a person's breath. This is done by analyzing the amount of ethyl alcohol in the breath, which is proportional to the level of alcohol present in the bloodstream.
Origin
The first breathalyzer device was invented in 1954 by Robert F. Borkenstein, a police officer with the Indiana State Police. Borkenstein developed the breathalyzer in response to the need for a more accurate and efficient way to test drivers for alcohol intoxication.
The original breathalyzer was a large, expensive, and complex device that required training to operate. However, over the years, breathalyzer technology has improved significantly, and modern breathalyzers are smaller, more affordable, and easier to use.
Today, breathalyzers are used by law enforcement agencies around the world to test drivers for alcohol intoxication. Breathalyzers are also used in other settings, such as workplaces and schools, to test for alcohol consumption.
