The AlcoBlow® handheld breath alcohol tester is an efficient and easy way to quickly gauge whether a person has consumed alcohol. The instrument uses a fuel cell detector which is the industry standard for law enforcement worldwide and offers many advantages over low-cost semi-conductor sensors used in consumer-grade products.

  • Students during school or special events
  • Inmates in correctional facilities
  • Work release program participants
  • Drivers at traffic roadblocks

  • Fuel cell sensor reacts only to alcohol
  • No warm-up time, always ready to use
  • Fast, easy testing sequence
  • Quick instrument recovery time allows for testing to be done on several people within a short time
  • Two modes of operation – Active and Passive – to fit any testing situation
