These graphs show how BACtrack Mobile and an Amazon-purchased novelty grade breathalyzer perform against the DataMaster, a police-grade breathalyzer using infrared spectroscopy. The graphs represent the testing of 8 different subjects over the course of two six-hour expanses. In total, 54 rounds of tests were conducted, each beginning with the gold standard police grade unit, the DataMaster, followed immediately with the BACtrack Mobile Pro and the novelty breathalyzer purchased from Amazon.com. In total, 162 tests were recorded.
As you can see, the test results of the BACtrack Mobile Pro closely mirror the DataMaster, especially at levels under 0.08% BAC. The novelty breathalyzer performs erratically throughout. Don’t risk wildly inaccurate results.
