Nanopuls have sold evidential breath alcohol testing systems to the Scandinavian police since 1989. Evidenzer®, developed by Nanopuls, is today the exclusive choice of the Swedish police, customs, and coast guard as well as the police in Ireland, Norway and Finland. Evidenzer has been evaluated by the Volpe Transportation Systems Center and found to meet the model specifications for evidential breath test instruments, as stationary or mobile device. Additionally, the National Highway Traffic Safety Administration (NHTSA) has reviewed and approved the Quality Assurance Plan (QAP) for the Evidenzer.
