How Do I Choose the Best Breathalyzer?

A breathalyzer is a device that measures your Blood Alcohol Content (BAC). Much like how blood test strips keep track of glucose levels for diabetics, BAC alerts the user to the level of alcohol in their blood at that given time. What may come as a surprise to you is that these handy devices aren’t just limited to law enforcement use. In fact, you can legally carry a breathalyzer for personal use in any US state. However, a breathalyzer should never be used to decide if you are indeed too drunk to drive. If there is ever any question or doubt, then you should not drive under any circumstance.

This device is best used to help your friends and colleagues make responsible decisions after consuming alcohol. And if you think about it, it’s much easier and less confrontational to convince a coworker, family member, friend, and even yourself, not to get behind the wheel when you have clear BAC results on hand. Essentially, a breathalyzer BAC result acts much like a thermometer would to prove to your child that they do have a fever or, similarly, as a blood pressure monitor would prove there was an issue to be addressed.
Breathalyzers come in a wide range of prices. Yet, when it comes to accurate BAC results, keep in mind that they are not all created equally. We came across an inexpensive breathalyzer for under $10. Nevertheless, we decided to forgo testing it. Why? Because we firmly believe that since this device is to be utilized in serious, health-related situations, then we should ignore models that may have been shabbily manufactured.

Fuel cell based breathalyzers render the best results, but are often pricier compared to non-fuel cell models. Additionally, the number of mouthpieces included with each device can also affect its price since buying them separately may be expensive (approximately $30 for 50 mouthpieces).
A breathalyzer can help you in two ways – it can save your life and it can save you from DUI fines or jail time. Therefore, it is imperative to buy a breathalyzer with appropriate features, regardless of pricing, since accuracy is of the essence.

Breathalyzers can be purchased with several different features, but here are a few aspects to consider when shopping for a good, reliable device.
  • Calibration – keep in mind that a breathalyzer needs to be calibrated to retain its accuracy. Some of the best breathalyzers are fitted with replaceable sensors to avoid recalibrating
  • Accuracy of the device – you can’t take any chances here, so look for the accuracy rating on the box or refer to the manufacturer website
  • Type of sensors – these dictate the accuracy of the device and the two options are fuel cell and semi-conductor. Essentially, both types of sensors provide great accuracy, but the degree of accuracy increases with the price
  • Display – most, if not all, portable breathalyzers have an LCD display that renders results right on its screen
  • Size – most devices are compact and lightweight so you can keep one handy at all times
  • Number of mouthpieces – most devices come with extra mouthpieces, but make sure that you can buy more in case you run out of them
  • Batteries – all devices are powered by batteries that are usually included in the package. Should you need to purchase them separately, they can be quite expensive.
Construction and Design
The most important feature of a breathalyzer is its ability to accurately measure BAC samples. Also, note that BAC levels fluctuate over time, where the highest levels are recorded half an hour to an hour after an individual has stopped drinking alcohol. Beyond that, you want a breathalyzer that’s easy to use with a clear display, otherwise it may be hard to convince an intoxicated friend of the results.

When it comes to the type of sensor, it is best to use a device that provides police grade accuracy. So, keep in mind that fuel-cell based devices are favored by law enforcement for their sheer accuracy, reliability and sensitivity. To briefly explain, this technology relies on an electrochemical process that generates an electric current, which is then measured by the device and converted into a BAC reading.
Performance and Ease of Use
Most breathalyzers are easy to use, and as mentioned earlier, are fitted with a small dimly lit bar. Reading and interpreting the results from the display can sometimes be frustrating, so check out devices that have big, bright or backlit numbers. Considering that this device is, essentially, a piece of hardware, it is bound to lose its accuracy over time. But, the good news is that most breathalyzers can either be calibrated yourself or by sending it back to the manufacturer.

With regards to battery life, most of these devices are good for more than a 1000 uses before the need to switch batteries. The majority of fuel cell breathalyzers take roughly 30-40 seconds to warm up before they can take a reading and render accurate results.
