BACtrack Breathalyzer Performance

These graphs are a comparison of how BACtrack Mobile and an Amazon-purchased novelty grade breathalyzer perform against the DataMaster, a police-grade breathalyzer using infrared spectroscopy. The graph represents the testing of 8 different subjects over the course of two 6-hour expanses. In total, 54 rounds of tests were conducted, each beginning with the gold standard police grade unit, the DataMaster, then directly after with the BACtrack Mobile Pro, and then the novelty breathalyzer purchased from Amazon.com. In total, 162 tests were taken.

As you can see, the test results of the BACtrack Mobile Pro closely adhere to the DataMaster, especially at levels under 0.08% BAC, whereas the novelty breathalyzer performs erratically throughout.
