Alcohol monitoring supports an individual’s sobriety while undergoing community-based treatment. Courts and agencies also need effective compliance and curfew monitoring solutions for individuals with DUI or high-risk alcohol use histories. The BI transdermal and breath alcohol monitoring devices accurately test and drive client sobriety, and results are court admissible in drug courts, divorce courts, and custody cases.

BI TAD - Transdermal Alcohol Detector

BI TAD®, or Transdermal Alcohol Detector, continuously monitors for alcohol consumption through a noninvasive skin sensor worn on a client’s ankle. TAD also includes radio frequency monitoring capabilities so clients can be monitored for curfews and alcohol use with the same device. If a client drinks alcohol while wearing a TAD ankle bracelet, the sensor detects a “drinking event” via sensible perspiration (sweat) and insensible perspiration (vapor) emitted through the skin.
