באַקטראַקק is a globally recognized leader in breath alcohol monitoring technology, providing accurate and affordable breathalyzers for both consumer and professional use. Based in San Francisco, the company (KHN Solutions Inc.) effectively pioneered the smartphone breathalyzer category, integrating fuel cell sensor technology—the same standard used by hospitals and law enforcement—into portable devices.

Their product lineup ranges from the compact C-series keychain testers to the professional-grade S80 and Mobile Pro models. BACtrack devices are designed to help users estimate their Blood Alcohol Content (BAC), understand how alcohol affects their bodies, and make informed decisions. The brand emphasizes safety, accuracy, and ease of use, with products widely distributed in North America and internationally.

• How long should I wait after drinking before using my BACtrack?

  You should wait at least 15-20 minutes after eating, drinking, or smoking before testing. Failure to wait can result in inaccurate readings and potentially abuse the sensor.

• What does the 'Flo' error mean on the display?

  This indicates that the user did not blow a sufficient breath sample. Press the start button to restart the cycle and ensure you blow firmly and continuously for the required duration (usually 5-6 seconds).

• How often does my BACtrack need calibration?

  For most models, calibration is recommended every 6 to 12 months or after a specific number of tests (e.g., 200-300), depending on usage and the specific model.

• What does the 'Out' error mean?

  The 'Out' message appears if no breath sample is detected within the allowed time window (usually 15 seconds to 3 minutes depending on the model). Restart the test and blow when prompted.

• Where can I get my BACtrack calibrated?

  You can obtain calibration services by visiting the official BACtrack website calibration page or contacting their support team for a Return Authorization.
