Breathalyzer test devices are typically categorized by one distinction: for personal, consumer use or for professional use. The difference between the two in the way that they function is that personal breathalizers generally use semiconductor sensors and professional breathalyzers generally use fuel cell sensors. Many personal use personal breathalyzer devices can be inaccurate. Professional types are always more accurate, but especially when testing higher blood alcohol content (BAC) can personal types of breathalyzers yield inaccuracy. Some inaccuracy that a personal breathalyzer could yield is results that come up false positive if taken from a person who is diabetic or on a low-calorie diet. The technology that is used in a breathalizer in the present day is generally limited to these three basic types listed below.
Types of breathalizer
Semiconductor oxide-based breathalyzers are one type of BAC analyzing device. This kind falls within the category of personal or consumer use. They are almost always very affordable, and they are also portable for ease of use. It’s a great idea to carry a breathalizer like this with you if you intend on drinking alcoholic beverages and plan to operate a vehicle later on. These kinds of breathalyzers are fairly new as well. They use an ethanol-specific sensor to determine BAC through blowing breath into a mouthpiece momentarily until the device gives a reading. Semiconductor types you will need to calibrate after every 300 uses. They are best used to detect alcohol, not for determine exact BAC.
A fuel cell-based breathalizer device is classified as a professional type of breathalizer. This kind of device is also one that uses breath samples to determine how intoxicated an individual may be. Fuel cell-based breathalyzers are also portable, but unlike the last device, are very accurate at determining BAC. This is how it works. It creates a chemical reaction with the alcohol to make an electric current that is measurable. The more alcohol that is in the sample of breath, the more a current is harvested. These kinds of breathalyzers are typically used by law enforcement and the testing of individuals who are suspected of driving under the influence.
Final breathalizer information
Spectrophotometers are the last kind of breathalyier device. These are professional breathalyzers that are used by law enforcement. Usually found in police stations, these devices are much more complex than any other kind of BAC analyzer. The method of measurement that spectrophotometers use is certainly the most accurate of them all and definitely the most efficient in terms of measurement. Although they are not portable, their ability to measure BAC is outstanding. BAC is determined by taking a look at the molecules of an individual’s sample of breath. You can observe the molecules at a microscopic level and analyze the way in which they absorb infrared light. Your BAC is measurable by the ethanol levels concluded to be present after the molecules are observed. Check out our breathalyzer reviews for the best on the net.
