Watch Out for Falling Surge Protectors – More Problems with the Intoxilyzer 8000

When Florida purchased the Intoxilyzer 8000 it needed an easy way to show a jury that the machine worked.

The Problem with Mouth Alcohol and Florida’s Intoxilyzer 8000

Why is Edward Owens, the former Agency Inspector for the Hillsborough County Sheriff’s Office, blowing twice the legal limit during his monthly inspection of the Intoxilyzer 8000?

Florida’s Missing COBRA Data for the Intoxilyzer 8000

Remember the Intoxilyzer 8000 Study in Which FDLE Employees Were Paid to Get Drunk?

Flow Sensor Calibrations: Why the Intoxilyzer 8000 Used for Florida DUI Breath Tests is Unreliable

Matthew Malhiot recently published an informative article discussing the Intoxilyzer® 8000: Flow Sensor Problems in Florida.
