The BACtrack SingleShot is a single-use disposable breath alcohol tester. For this 0.02 %BAC version, the crystals will change color if the users alcohol level is at or above 0.02 %BAC. The SingleShot .02 is perfect for zero-tolerance environments like schools, businesses, and for family use. Simply squeeze the center of the tube to activate the test, and blow through the SingleShot. Based on your Blood Alcohol Content (BAC), the crystals will either stay yellow indicating a negative result or change to blue/green, indicating a positive result. For example, the SingleShot .02 will indicate "positive" by changing color when the user's alcohol level is at or above 0.02 %BAC. The BACtrack SingleShot is over 99% accurate and provides rapid results. Because of its extremely small size, it is easy to store anywhere: in a pocket, purse, or even car glove compartment. It can withstand extreme temperatures in winter and summer as the acceptable storage range is from 4 to 122 degrees Fahrenheit (-15 to 50 degrees Celsius). The SingleShot also has a long shelf-life, 3 years from the manufacture date. This is the perfect product to always keep on hand to check your Blood Alcohol Content.
