Tips on How to Pick The Personal Breathalyzers
You probably know breathalyzers as a tool used by law enforcement, but there’s actually a huge array of industries and applications for personal breathalyzers. On top of that, a personal breathalyzer can be very handy to keep an eye on your blood alcohol level (BAC) and how much influence alcohol has over your body.
Choosing the Right Breathalyzer
Personal breathalyzers are designed to help ensure you’re under the legal drink-drive limit when you take the wheel the morning after a night of drinking and celebrating. There’s a wide choice, between basic semiconductor devices and fuel-cell products, costing from a few dollar to over $100.
Semiconductor sensors are typically used for breathalyzers undergoing low-volumes of testing. They’re a cheap and simple option for casual home use. For regular use, semiconductor sensors will need calibration at least twice per year to maintain their moderate degree of accuracy.
But for reliable accuracy and any significant volume of testing, you’re going to need something stronger. Fuel cells are better at providing both highly accurate and more consistent BAC results.
Using a breathalyzer is simple. A user, using his mouth, just blows into the nozzle of the tester and the instrument instantly displays the BAC (Blood Alcohol Concentration) up to 3 or 4 digits. The rule of thumb is to wait for at least 10 minutes from the moment you’ve consumed alcohol in order for the device to produce reliable results.
