The National Highway Traffic Safety Administration preserves a list of Evidentiary Breath Testers approved for court permissible outcomes, rated by their manufacturer versus police-grade instruments for accuracy, reliability and performance. One study performed utilizing home breathalyzers revealed all 7 devices undervalued BAC by more than 0.01% and two stopped working to properly discover BrAC levels equaling those determined with police-grade gadgets. The very best breathalyzers are made in the US with fuel cell or semiconductor sensing units and utilized by law enforcement and federal government agencies across the world.
