Abstract: The technologies described enable tracking statuses of and performance metrics for alcohol sensing devices, with respect to performing device integrity checks in order to ensure that testing of provided samples is performed properly. Systems described include alcohol testing devices including flow tubes, alcohol sensors, pumps, supplementary sensors, processors, and user interfaces. Methods described include steps for performing a set of integrity checks in coordination with receiving samples (e.g., breath samples, transdermal samples, etc.) from users.
