Residual Mouth Alcohol and Gastroesophogeal Reflux
The BAC DataMaster and the Intoxilyzer 8000, Ohio’s most common breath testing instruments, further guard against this type of problem with “slope detectors” which look at the air coming into the machine. If the air is too heavily laden with alcohol it changes the shape of the curve and should result in the machine kicking out an “INVALID SAMPLE” reading. This reading requires the officer to start the observation period over again. Good DUI/OVI attorneys will know the science behind the “slope detector” and its operation and can effectively explain this to a jury. Charles M. Rowland II is a certified operator of the BAC DataMaster and the Intoxilyzer 8000.
