Breathalyser for your car

An alcohol tester (a breath-alcohol analyser) is designed to measure the alcohol content in the air a person breathes out. To get a sample, the subject blows into a special hole in the device. The sensor measures the alcohol concentration and the result is displayed on the screen.

Alcohol testers: 9 key facts

1. These devices can be used for self-testing before getting behind the wheel. They are also used by police to test for alcohol intoxication. In factories and safety-critical environments, they are sometimes used to test employees for sobriety. There are also specialised devices, such as those designed for testing large groups of people.
2. Professional instruments are more accurate and efficient; they are accurate to 0.01 ppm and capable of taking approximately 250 air samples a day.
3. The most common type is the electrochemical (fuel cell) kind. It has a quick response, high sensitivity to ethanol vapour, and stable operation in hot and cold weather.
4. Infrared sensors are highly accurate but take a long time to process the data. They are sensitive to ambient temperature, and so are mainly used in labs.
5. Personal breathalysers need calibrating every two months while professional ones need to be calibrated at least once a year. Calibration is performed by special service centres.
6. If the instrument is designed with a mouthpiece, this has to be changed after every test. It is recommended to use only components that are compatible with the particular model.
7. To get accurate results, tests should be taken at least 20 minutes after smoking, eating, or drinking alcohol. The person being tested should exhale steadily and deeply.
8. To keep the sensor working properly, you should prevent cigarette smoke or liquids from getting into the opening.
9. High-tech devices give a warning if the subject provides an insufficient sample; an accurate test is only possible when there is sufficient amount of exhaled air. Mouthpieces with a non-return valve serve the same function.
