Top 5 Best Personal Breathalyzer Deals


Ideal for “party holidays” like St. Patrick’s Day, Cinco de Mayo, or Spring Break, a breathalyzer can help you make sure that you are drinking responsibly. You simply blow into the breathalyzer, and the device can calculate your blood alcohol level. With that info, you will know if you are safe to drive. Just in time for St. Patrick’s Day, we’ve rounded up the best deals and discounts on a variety of personal, portable breathalyzers. Whether you want something keychain-sized, something low-tech, or an option that’s top-of-the-line, here are five great deals on breathalyzers.

1. AlcoHAWK PT500 Breathalyzer Alcohol Detector

best breathalyzer


AlcoHAWK is one of the leading names in the personal breathalyzer industry. They have a couple of different models, including the low-cost AlcoHAWK Slim. However, we like the more premium PT500 model more than the Slim. The PT500 uses “PT Core Sensor Technology,” which is designed to minimize the risk of scoring a false positive. The display is nice and large, and it’s back-lit to boot. When using this display in the dark, or after a few beers, it is still easy to read.

Another nice feature that you’ll likely appreciate after having a few drinks is the presence of both an audio and visual warning when you are over the limit. The BAC alarm can be adjusted to your preference. This breathalyzer can measure BAC range from .000 to .400 percent.

If you’re looking for a breathalyzer you can share with friends, family, or roommates, this is a solid choice. This unit has replaceable mouthpieces that are individually wrapped. If you choose this particular model, or any other breathalyzer on this list, make sure to follow directions for your particular breathalyzer exactly to get the most accurate results. Drink responsibly. Never drink and drive.

Price: $104.99 (48 percent off MSRP)

2. BACtrack Go Keychain Breathalyzer



A breathalyzer is a great tech accessory to have in your arsenal, but it only works if you remember to take it with you. An ultra-portable keychain breathalyzer lets you keep your BAC meter right on your keys, which is perfect for those nights when you’re going out to have a drink.

BACtrack’s Go Keychain breathalyzer is a great option for personal use, though it’s not the most sanitary option for those who need a shareable BAC meter. Only three mouthpieces are included. The mouthpiece folds in for easy storage. The LCD display is a bit on the small side, but this is still a solid choice for people who need a small, ultra-portable BAC tester. For best results, only use this tester after at least 15 minutes have passed since you finished your last drink.

As of this writing, Amazon is offering an additional $5 off coupon for this portable keychain breathalyzer.

Price: $30.39 (24 percent off MSRP)

3. Alcohol Test Breathalyzer Tester (Disposable)


(Alcohol Test)

What happens to your fancy breathalyzer when your batteries die? Unless you have a backup battery handy, you’re out of luck. That’s one reason we like these decidedly “low tech” drink-a-lyzers from Alcohol Test. To operate this BAC test, you simply blow into the chamber.

Within the chamber, there are color-changing crystals. The color of the crystals indicates whether you have a O percent BAC, a BAC of 0.04 percent, or a 0.08 percent BAC. These types of test are nice because they are disposable, discreet, and doesn’t involve collecting any digital data. You can use these disposable tests by themselves, or to confirm your readings from an electronic reader.

Price: $35.97 for a ten-pack (40 percent off MSRP)

  • Test do have an expiration date

It connects to your smartphone using Bluetooth, and takes mere seconds to give you your results. Within the app, you can see estimates on how long it should take you to get sober.

Other features of the Breathometer app include the ability to find nearby lodging, or even the ability to call a car through Uber so you can get home safely.

5. BACtrack Trace Professional Breathalyzer



This BACtrack tester offers police-grade testing technology, and it’s one of the best-reviewed personal breathalyzers out there today. Built-in memory means that the last ten BAC tests you run will be stored locally. This can be either a good thing or a bad thing, depending on your outlook. Some people will appreciate having a record of their past tests, so they can see how their BAC has descended over the course of an evening. It’s also nice to have a reference for your own peace of mind. That being said, others may have privacy concerns about a device that tracks their personal data.

As of this writing, Amazon is running a promotion where you can use an additional $10 off coupon to buy this breathalyzer model. That makes this expensive model a bit more affordable. It takes readings very quickly, and has impressive accuracy.
