Breathalyzer Buyers Guide
Safety behind the wheel is paramount and drinking and driving should never be combined. This is why it is always good to have a breathalyzer to hand. Not only are many of the compact and convenient, but they can use the same technology as law enforcement. To be honest, this is only the case with certain brands, so it is important to know what to look for.
To make sure you are driving when it is safe, and are not going to compromise the safety of you and your passengers and others, we have created the following buyer’s guide.
What To Look For In A Breathalyzer
Above all else, the device needs to be reliable and work when you need it to. The better products are accurate and use similar or the same technology as professionals. This being said, any breathalyzer using semiconductor technology should be avoided as they are not reliable in the same way.
This starts with the warm-up time for the device which should be up to 20 seconds for most reliable brands. Then, the time it requires for the user to blow should be no longer than 5-6 seconds as not everyone can blow for much longer. Then, there is the waiting for the results. All in all, the whole process should be finished within a minute.
After this, the time the results stay on screen can be important and most will stay there for at least 15 seconds.
Easy To Read Display
The LCD screen needs to be easy to read but also give additional information. Having 4 digits in a readout is going to go a long way towards knowing if it is safe to drive or not.
Convenience is key as it is best to be able to store the breathalyzer in a bag or glove compartment of a vehicle. There are some that double up as key chains which means they have to be small. Most brands make sure their product does not measure more than a typical smartphone, with many being much smaller.
For additional readings and information, it can be better to purchase a breathalyzer that is compatible with a smartphone. This can give estimates as to when the BAC level will reach zero among other useful information.
The number of mouthpieces is more important than ever with hygiene being at the forefront of many people’s minds. Most are wrapped and sealed so whoever is using the breathalyzer can do so in the confidence that it is safe to do so. Many can be used more than once to ensure that it can be used whenever it is needed.
As with any piece of technology, it is always best to protect your purchase. Most brands tend to offer a year which can be enough to get some good use and piece of mind.
What Is A Fuel Cell Breathalyzer?
Using electrical current to measure the alcohol levels once detected, these are some of the most popular. Used by law enforcement officials around the world, fuel cell analyzers measure the number of electrons produced, and the more they are, the greater the electrical current will be.
Because they do not require a lot of power to work, this approach can be used time and again without draining batteries. They are favored because they are affordable and accurate but do require the user to wait at least 20 minutes after their last drink as they are not as accurate at retrieving readings from deep in the lungs.
How Accurate Are Personal Breathalyzers?
This very much depends on the device as there is a difference in quality. The first thing to look for is the type of technology used with fuel cell being the most preferable and semiconductor being the least reliable. Some have the backing of law enforcement which is always a good sign – look for these and reputable brands.
How Often Do Breathalyzers Need To Be Calibrated?
Most will arrive calibrated and ready to go but it is a prudent idea to re-calibrate every 12 months. For this to be done, the breathalyzer will need to be sent to the manufacturer directly and most brands will provide information on the frequency and where to send it.
Are Breathalyzers Any Good?
With a reliable product, yes they are good. The alternative is not driving after any alcoholic beverages to stay on the safe side. For many people, convenience is a major plus point, but reliable products work for many years, providing numerous accurate readings.
What Are The Benefits Of Using A Breathalyzer?
We’ve mentioned the convenience, but this is only the tip of the iceberg. The extensive benefits include the fact that they can save lives, preventing someone from getting behind the wheel when they are not sober. Also, it can stop a driver from losing their license, or facing a hefty fine. These fines start in the hundreds but can reach the thousands in certain circumstances.
The other benefits include their accuracy as trying to work out alcohol levels based on units consumed is not a reliable way of judging sobriety. Everyone is different and there are numerous factors that come into how alcohol is absorbed.
What Is The Best Breathalyzer?
After reviewing numerous products, we found the best available to be BACtrack S80 Breathalyzer. It is a professional grade product that only takes 10 seconds to deliver results after the user has blown for 5 seconds. It is also one of the most accurate, using fuel cell technology. We like that it is DOT approved in 50 states and has a solid reputation for being one of the more reliable personal breathalyzers on the market.
How Much Does A Personal Breathalyzer Cost?
The short answer is – not as much as a fine for drink driving. Most reputable brands are available for well under $150. There are products under $50 but this is where it is important to do more research into the technology used and reputation of the brand.
