The BACscan F-40 alcohol tester is a compact handheld device designed to measure blood alcohol concentration (BAC) in the range from 0% to 4% with stated 1% accuracy. It includes a clear LCD display for numeric readout and operates on a single 1.5V AAA alkaline battery, offering portable, single-handed operation. With dimensions of 47 mm width, 24 mm depth and 114 mm height, the BACscan F-40 is intended for personal use and small gatherings where quick breath-alcohol checks are needed.

Advantages

The tester provides a simple numeric LCD readout that removes ambiguity when interpreting results. Its measurement range up to 4% covers typical breath-alcohol levels encountered in personal and social contexts. The device’s compact size and low power requirement make it convenient to carry and use without frequent battery changes. The straightforward operation reduces the learning curve for non-professional users seeking a basic quantitative indication of alcohol level.

How to use

Insert a fresh 1.5V AAA alkaline battery into the device according to the polarity markings. Power on the unit and wait for the display to indicate readiness.

Allow time between tests as indicated by the device to ensure accurate readings; do not attempt sequential tests without observing any warm-up or recovery intervals suggested by the unit.

Recommendations

Use the BACscan F-40 as a preliminary screening tool only. It is suitable for personal monitoring but not a substitute for professional or legal-grade equipment. Ensure the battery is in good condition, follow the device’s warm-up and measurement timing, and avoid eating, drinking, or smoking immediately before a test to reduce interference. If precise or legally binding measurement is required, seek a calibrated professional breathalyzer or laboratory testing.
