BACtrack C8 Breathalyzer Alcohol Tester — Pocket-Sized with BluFire Fuel Cell & App

The BACtrack C8 is a pocket-sized breathalyzer that gives fast, professional-grade estimates of blood alcohol concentration with optional smartphone pairing.

Small enough to carry in a purse, pocket, or glove compartment, the BACtrack C8 uses the same BluFire fuel cell sensor technology found in professional devices to provide dependable breath alcohol readings. You can use it on its own for quick results or pair it with the BACtrack app to log tests, view trends, and use the ZeroLine feature to estimate when your BAC will return to 0.00%.

How accurate are the BAC readings from the C8?

The C8 employs BACtrack’s patented BluFire Fuel Cell Sensor — the same sensing method used in clinical and law-enforcement equipment — giving you lab-grade sensing in a consumer device. While not a legal-determination device, it delivers consistent, repeatable BAC estimates useful for personal decision-making.

• Professional-grade fuel cell sensor for higher reliability
• Designed for consistent readings across multiple tests
• Not intended as a substitute for official breathalyzer tests

What does the ZeroLine feature do and how can it help me?

ZeroLine estimates how long it will take for your blood alcohol concentration to reach 0.00% based on your current reading. This helps you plan safe timelines for driving or other activities, and gives a clearer picture of alcohol elimination than a single number alone.

• Displays estimated hours until BAC returns to 0.00%
• Works with the BACtrack app for trend tracking
• Provides context beyond a single BAC percentage

Can I use the BACtrack C8 without my phone?

Yes — the C8 is fully functional in standalone mode and will show BAC results directly on the device. If you choose to connect, App Mode transfers readings wirelessly to the BACtrack smartphone app for history, graphs, and additional features.

• Standalone Mode: quick on-device readings without a phone
• App Mode: Bluetooth transfers results to the BACtrack app
• Easy switching between standalone and connected operation

How portable and durable is the device for everyday use?

The C8 was designed as a mini handheld breathalyzer that fits into common daily carry spaces like pockets or small bags. It balances a compact footprint with a robust sensor and includes a one-year warranty for peace of mind.

• Compact size for purse, pocket, or car storage
• Rugged construction suited to regular handling
• One-year repair or replacement warranty

Who this is for: The BACtrack C8 is aimed at responsible adults who want an accessible, accurate way to estimate their blood alcohol concentration before making decisions about driving or activities. It’s ideal for people who value portability, prefer the option to use a device independently, and appreciate the added data and logging capabilities when paired with a smartphone app.
