Yes, we offer the BACtrack SingleShot, which is a disposable, single-use breath alcohol tester available in three %BAC thresholds: 0.02%, 0.05% and 0.08%. The BACtrack SingleShot is based on indicator chemistry that changes color in the presence of breath that contains alcohol.
A user will activate the small tube tester, blow through the SingleShot, and the crystals will indicate a positive or negative result based on the Blood Alcohol Content (BAC). For example, the SingleShot .02% will indicate "positive" by changing color when the user's alcohol level is at or above 0.02% BAC. These units are accurate, inexpensive, and extremely small, which makes them easy to carry in a pocket.
