alcohol sensor fuel cell
Portable breathalyzers for personal use are growing rapidly in popularity. Sales in the U.S. increased by only 23 million U.S. dollars in 2005 to more than $ 200 million in 2009.
Several factors underlie this. One, obviously, is a tougher approach to driving by the law enforcement authorities. But another is that the prices of these devices are dramatically reduced, while at the same time, the technology improves. If you search around you can find personal breath testers for sale for as low as $ 5, but for that kind price you will buy anything that has a high probability of a dangerous error.
So here are five questions before buying a blow pipe:
* Why would I? Many people buy these devices as a kind of party novelty. They are fun to use at parties and other social events to see who is the most popular. If this is your goal, a cheaper model will suffice. But if you are seriously worried that caught driving across the border then you need an expensive device.
* Is it really accurate? The cheap ones - by about $ 20 or $ 30 - are quite unreliable. The best ones are based on fuel cell technology, which is also used by law enforcement agencies. Among these are semiconductor sensor models, which come in a range of prices. This technology has advanced rapidly in recent years, and the best semiconductor sensors are very good.
* Is it approved by the Food and Drug Administration? In theory, this is mandatory for all breathalyzers, the FDA classified as medical devices, but In fact, many do not have this approval.
* Is it necessary mouthpieces? Some personal breath testers use to blow up without the device. However, this permits outside air to mix with your own breath sample, making the reading unreliable.
* Can it be recalibrated? Breathalyzers may gradually decline in accuracy. If you plan on using your phone for a reasonable time (say, more than one year), look for a more expensive model that can be sent away to be re-calibrated.
And remember, the best way to ensure that you are not arrested for drunk driving is to refrain from drinking and driving. Find someone else to ride for you. Or stay home. There are far better things to do than go out and get drunk.
