A breath alcohol tester (also known as a breathalyzer) is a device used to estimate the concentration of alcohol in a person's bloodstream by analyzing a sample of their breath. It measures Blood Alcohol Concentration (BAC), providing a quick and non-invasive method to determine if an individual has consumed alcohol and whether they are over the legal limit for activities such as driving.

The tester works by detecting alcohol molecules in the breath, which correlates to the alcohol level in the blood. When a person blows into the device, sensors within the tester, typically fuel cell or semiconductor sensors, react with the ethanol in the breath and convert it into an electrical signal. The device then calculates and displays the BAC percentage on a screen.

Breath alcohol testers are commonly used by law enforcement, employers, and individuals to prevent drunk driving and ensure compliance with legal alcohol limits.

The Alcoholmeter gives readings for Alcohol By Volume at 20 degrees Celsius. Thisalcoholmeter has calibrations for 0 to 100% abv. An alcoholmeter is used to findthe alcohol percentage of alcohol by volume (abv) in completely dry or distilled liquor.Because an alcoholmeter measures the density of the liquid compared to that ofalcohol, any residual sugar or other cause of change to the density will result in afalse low reading. Because there is often a minute amount of unfermented sugarfollowing standard fermentation, along with dissolved carbon dioxide and spentyeast or solids remaining after fermentation, it is very difficult to obtain an accuratereading of the abv in such a liquid. In addition, an alcoholmeter is increasinglydifficult to read lower alcohol percentages, compounding the problem. For thisreason, it is suggested that you use an alcoholmeter only for the testing of distilledspirits.
