10 best breathalyzer for alcohol keychain

A breathalyzer for alcohol keychain is a portable and compact device designed to measure a person's blood alcohol content (BAC) by analyzing their breath. These keychain-sized breathalyzers are commonly used for personal use, allowing individuals to check their alcohol levels before driving or making important decisions. Here's some information about breathalyzer keychains:

  1. Functionality: A breathalyzer keychain typically works by having the user blow into a small tube or sensor. The device then analyzes the alcohol content in the exhaled breath and provides a numerical reading of the person's estimated BAC.

  2. Accuracy: While breathalyzer keychains can provide approximate BAC readings, they may not be as accurate as professional-grade breathalyzers used by law enforcement. Factors such as calibration, sensor quality, and user error can affect accuracy.

  3. Use Cases: These keychain breathalyzers are often used by individuals who want to monitor their alcohol consumption, especially before driving. They can help users make informed decisions about whether they are fit to operate a vehicle.

  4. Portability: The small size of keychain breathalyzers makes them convenient to carry in a pocket, purse, or on a keyring. This portability encourages users to have the device readily available when needed.

  5. Battery-Powered: Most breathalyzer keychains are battery-powered, typically using small disposable batteries. Some models may have rechargeable batteries for convenience.

  6. Digital Display: These devices usually feature a digital display that shows the BAC reading in numerical form, making it easy for users to interpret the results.

  7. Precautions: It's important to note that breathalyzer keychains are not a foolproof measure of sobriety or fitness to drive.They are best used as a rough estimate and should not be solely relied upon. If you plan to drive or engage in activities where alcohol consumption is a concern, it is always safer to use a designated driver or alternative transportation.

  8. Maintenance: To maintain accuracy, some keychain breathalyzers may require periodic calibration or replacement of sensors. The user manual that comes with the device should provide guidance on maintenance.

  9. Legal Considerations: The legal BAC limit for driving varies by jurisdiction, so it's important to be aware of the local laws and regulations regarding alcohol consumption and driving.

While breathalyzer keychains can be a helpful tool for personal awareness and safety, it's crucial to remember that they have limitations, and their readings may not always reflect your true level of impairment. If you have consumed alcohol and are unsure about your ability to drive safely, it is always best to err on the side of caution and avoid getting behind the wheel.

User questions & answers

Question: Does it come with disposable breath attachments
Answer: Yes, this comes with three mouthpiece covers. However, they are washable and reusable, so you do not need to dispose of them after one use. Additionally, the device will work without the mouth piece covers, as there is a fold out mouthpiece for you to breathe into during the test. The covers are more for sanitary reasons when sharing your BACtrack with others.
Question: How many tests can you do? Does it have to be recalibrated after so many tests
Answer: Hello, Thank you for contacting BACtrack Customer Support. The calibration service helps ensure the unit is working within specification and providing accurate results. There is a general recommendation of around 200 tests or once per year before sending this unit to be serviced. You would place a calibration order online on our website and then receive an email containing instructions on where to send the unit to be serviced. Please contact our customer support center at (415) 693-9756 for more information or assistance with placing a calibration order. Best, John Olson BACtrack Customer Support

User questions & answers

Question: Has anyone run this through fakespot.com to see if there are a lot of unreliable reviews
Answer: I updated my own review and I would not trust this at all. It's a novelty and very unreliable.
Question: What happened to the $20 off coupon or rebate
Answer: WHAT HAPPENED TO THE $20 OFF COUPON? I want to buy another one, and it went away.
Question: Does this machine measure Ketone levels
Answer: I just did the research and yes, it will. Ketones are measured through the alcohol in your breath and a raise in Keytone’s will also raise in your alcohol levels even if you have not consumed any. A good reading would be around 0.4-0.5 especially when you have not consumed any alcohol whatsoever. That is a good sign that you are indeed in ketosis. This can be done with any breathalyzer, especially a cheap one.
Question: Is the removable mouthpiece required if you only use it yourself and not in groups
Answer: Thank you for contacting BACtrack support through Amazon. It is not required that you use mouthpieces with the BACtrack C6. Also, each BACtrack C6 ships with 3 mouthpieces.

User questions & answers

Question: Does the 15 minute wait period include drinking water
Answer: These mouthpieces will only fit on the BACtrack Keychain Breathalyzer.
Question: How do I change the battery
Answer: Hello That means the unit is out of calibration period so needs to be re-calibrated by our expert technician. Please contact us at [email protected] or call us at 310.490.4652 and let us know your Amazon order # Thanks.
Question: Does it keep track of your high score
Answer: Thanks for your question. As explained on the manual, your breath sampling is inconsistent or too weak to analyze your breath sample. Please blow steady and continuously(without any stopping) until hearing click-clack sound.
Question: Why wait exactly 15 minutes? What happens if you wait 20 or 180? It seems a lot to expect drunk people to be that accurate
Answer: Thanks for your question. It has 12 months & 1,000 tests of calibration intervals as a default setting (whichever comes first). So the unit will give you alert on the display when the recalibration service required.

User questions & answers

Question: can you measure ketones with this
Answer: I towed a lifted 1996 Toyota 4-Runner out of a creek with it, wasn't recommended and granted anything that happened was on me but it didnt torque it in any way. I also managed to get a tree in between this step and my bumper, a tree taller than my jeep but about 5 inches thick, when I tried I go forward I thought I was stuck and when I stepped on the gas it broke the tree in half and bent it a tad. My opinion, if you intend to use this as its intended then you will never have a worry. Even me wit as much crap I've put this thing through I wouldn't sell it for less than $60 right now lol.
Question: Is there not an app that tracks history of test for this specific breathalyzer
Answer: Very happy with it
