This can mean that you end up with an accuracy rate of about +/- 0.01 at 0.100% BAC.
So, if you want on the nose readings each and every time, this may not be the best device for you.
There is no denying, though, that this is rather an easy Breathalyzer to manage since all you need to do is to power it up and blow into it.
The good news, nonetheless, is that this is not a device that needs to be calibrated.
This is because all you need to do is to replace the sensor and it will be working as well as when you first got it. This will save you an incredible amount of time and trouble.
One of the other minor complaints about this device is that the numbers appear on the screen only for a short time before it goes dark.
While this does help to save the battery, it isn’t great if you aren’t quick on the uptake.
- Easy to use
- Doesn’t need to be calibrated
- Has issues with consistency
- Results don’t appear for very long
Things to Know When Buying a Breathalyzer
Ok, now that you know what your best options for breathalyzers are, it is time to go through the process of choosing one.
Types of Breathalyzers
For the purpose of this guide, we will just be focusing on the technology that is used in portable and personal breathalyzers.
So, with this in mind, it is safe to say that there are two main types of devices. They can be differentiated by the type of technology that they use.
These are the oxide semiconductor sensors and the fuel cell sensors.
Oxide Semiconductor Sensors
These sensors make use of small, metal oxide beads. This relies on a voltage that changes when it comes into contact with alcohol.
When this happens, the change in the current is registered and the breathalyzer determines the alcohol content in your breath.
Now, one of the main benefits of this type of sensor is that it is affordable. Thus, you will find cheaper models with this technology.
Unfortunately, it isn’t all that difficult for this sensor to be deceived. This is because it also has a tendency to register ketones as alcohol.
This can make it a bit difficult to rely on the readings that you get with this type of sensor.
Fuel Cell Sensors
Fuel cell sensors, on the other hand, have the benefit of being as good as most devices utilized by the police and other authorities.
This technology relies on the oxidation of the alcohol in your blood. When this occurs, there is a voltage that is generated.
Thus, the greater the amount of alcohol, the greater the voltage that is generated.
As you can imagine, this kind of technology isn’t the cheapest so you will have to have to part with $80 or more for this kind of model.
On the upside, it is worth every penny.
The Main Features of a Breathalyzer
Now, let’s consider the main features of any good breathalyzer:
The most important thing for anything breathalyzer is the level of accuracy that it is able to maintain. After all, without this feature, your device is essentially useless.
It should be noted that not even the police boast portable breathalyzers that are a 100 percent accurate.
The only real way to get a proper understanding of your blood alcohol level is with a blood test.
This means that your personal device does have some wiggle room. Ideally, your breathalyzer should fall within 0.01 g/210 L if it wants to be accurate.
In a perfect scenario, your device would register precise results. However, if it should provide you with slightly higher results, this is forgivable.
Under no circumstances, though, should the breathalyzer ever register lower results than your actual blood alcohol level.
The thing about personal breathalyzers is that they need to be calibrated every once in a while. This is because, after a while, these devices have a tendency to become saturated.
When this happens, there is a greater likelihood of the readings being incorrect.
To avoid this, most breathalyzers require you to send the devices in so that they can be calibrated by the manufacturer.
This option has a few disadvantages. The first is that every time you want to do this, you are going to have to spend between $20 and $30.
On top of this, you will have to make do without your device until it is returned you.
There are some devices that don’t require calibrations. In these instances, the sensors on the device have to be replaced.
While this may cost you some money, it has the advantage of allowing you to keep your device with you at all times.
If you are being honest, you will only be using a breathalyzer when you have had at least two drinks. So, your dexterity may not be at its peak.
Due to this, it is always important to determine just how easy a device is to use when you aren’t functioning at full capacity.
The fewer buttons involved, the easier it will be for you.
That doesn’t mean that there aren’t some advantages to having a myriad of settings to choose from.
When there are a greater number of settings, you can customize the device to better suit your preferred units or mode of function.
In this way, you may actually find it easier to use.
Things to Look for When Buying a Breathalyzer
Here are some tips that you can follow when looking for a breathalyzer:
- Price: with breathalyzers, you will often find that splurging can actually come in handy. Typically, the pricier options often offer a greater level of accuracy and are of better quality as well.
- Size: you probably want to take your Breathalyzer with you to bars and parties. So, the last thing you want is something that is large and clunky. Look for devices that can fit in the palm of your hand and that can discreetly be placed in your pocket or your bag.
- Large Display: these readings aren’t something that you want to get wrong. This is why you should opt for a larger screen so that you can easily see the numbers, regardless of the time of day.
- Audible warnings: if numbers just won’t do, you may want to look for a model that provides you with an audible warning. Here, the device will produce a noise when you are considered too intoxicated to drive.
With all this information on hand, you will be able to decide on a breathalyzer that is perfectly suited to you.
If you value accuracy above all else, then you are going to need to get yourself the BACtrack S80 due to its high precision rate.
However, if you want a model that is affordable yet accurate, then the AlcoHAWK PT500 will prove to be a good choice. The AlcoMate Revo TS200 is suitable for anyone looking for a fuss-free option for their breathalyzer.
If you want a device that is simple to use but still has a lot of features, then the BACtrack Trace Professional device is best.
This brings our guide on breathalyzers to a close. You should now have all the information necessary to make an informed decision for yourself.
