BreathKey Breathalyzer - The Digital Keychain Breath Alcohol Tester with Professional Features

BreathKey Breathalyzer

Since 1938, the portable breathalyzer or drunkometer as it was called at the time, has been used by law enforcement to curb drunken driving.  Since 1954, the first practical breathalyzer was used by people to find out whether they are fit to drive or not after a round of drinking alcohol.  Ever since the portable breathalyzers became smaller and even easier to use, they are being used everywhere where blood alcohol content is in dispute.

Here is a list of popular breathalyzers being sold on Amazon.com for some great prices.

Probably the only difference between a portable breathalyzer in 1938 and 1954 and the modern ones are the way alcohol is detected and measured. The earliest types of portable breathalyzers use a chemical reaction to show the amount of alcohol whereas the latest versions of the portable breathalyzer use what’s called a ‘fuel cell’ reactor to detect the amount of alcohol and measure its amount. The way it’s detected has also undergone a big change in the sense that in the fuel cell reactor, the amount of alcohol generates electricity that’s proportional to its amount.

Are very small as well, with some models being so small that you can attach it to a keychain and keep it in your pocket while the rest of the brands and models are small enough to put in a purse or handbag.

All modern portable breathalyzers have one thing in common in that it gives a readout of the amount of alcohol in percentage by volume and the legal limit on how much alcohol that you can take is 0.08%. Not to say that most modern portable breathalyzers are very accurate, but if you follow the instructions in the manual, you will get a fairly accurate reading that may be on par with the calibrated readings of the portable breathalyzers the police usually use.

Most portable breathalyzers do have a lifespan in which you can take readings, though. For most portable breathalyzers, you can take 200 to 300 readings before you may need to take it back to the manufacturer for recalibration. Remember that anything that’s used over and over will wear down eventually and portable breathalyzers are no exception. Not even the human body is exempted to this rule.

The function of the recalibration is to return the portable breathalyzer to its original factory condition with regards to its fuel cell reactor. Think of it as its periodic maintenance schedule and the manufacturer may charge you for the recalibration. Unfortunately sending the unit back is the only way to have it recalibrated since the manufacturer has the technology to recalibrate its products, as there is no known service center for these products anywhere, unlike computers.

Like most other electronic equipment, portable breathalyzers need to have a power source to power itself. With most models, replaceable batteries are used but there are also models that have unserviceable batteries and must be sent back to the manufacturer when you need it for recalibration or when the internal batteries refuse to charge.

Portable breathalyzers offer another way to know how much alcohol you have drank and with some people, how fast their bodies metabolize alcohol after ingesting it. Research, I guess. Regardless of what use you have with a portable breathalyzer, it’s another way for you to avoid getting stopped for a DUI after drinking.
