Don’t Drink and Drive
A Breathalyzer is a device that is used to measure the blood alcohol level in a human being. An alcohol tester is not an accurate device to measure blood alcohol levels, it just gives a good estimate.These are devices used by the agencies that enforce law on the citizens, especially to check whether people who drive motorised vehicles are drunk or not or are suspected to be above the legal limit allowed. The Breathalyzer unit is about the size of the digital camera with a plastic inlet pipe attached.
The person who is supposed to be tested for drunken driving is told to take a long deep breath and then exhale all the air in his lungs into the pipe. The machine unit then runs a test, with some complex reactions to give the level of alcohol that is present in the blood. Some units also use colour coding to determine the level of alcohol. These breath analyzers are generally available for the police force, but now even common public can buy them. People buy these units to check the blood alcohol levels before they start driving to avoid getting caught on road. They are also used at discos and pubs.
Breathalyzers are now available online at the click of a button. It is very easily available and so many people buy and regularly use it. There are different types of Breathalyzers available, Industrial type of testers, personal alcohol testers and fixed type of testers. Their prices vary from 100$ to 500$ and above. These testers are also available in mini sizes and big ones for professional use. The professional alcohol tester can also be operated in the dual mode, one to measure specific blood alcohol concentration and the other as an alcohol responder between multiple people to measure the presence of alcohol.
The mouth piece is an important accessory of the tester and is provided along with the machine. All breath alcohol testers display BAC ( Blood Alcohol Concentration) based on the information stored in the sensor s memory. These values are stored in the tester to give the most accurate readings. But over time, these values lose their accuracy and do not show correct readings. In order to regain their accuracy, the tester has to be recalibrated to refresh the sensor values.
Buying a breath alcohol tester is very advantageous these days, because it is better you test you blood alcohol levels before you start driving. It will avoid your having an accident as well as paying a hefty fine if you get caught.
