The Intoxilyzer 400 was specifically designed for employee testing programs, is easily transported for onsite testing, and is fully automatic. Better yet, it automatically counts down during the 15-minute wait time. The I-400 can be used in testing regulated by DOT, NRC, and DOE. NOTE: This device does not have a keyboard but the results print out very easily using a printer designed specifically for the I-400.

  • Three testing modes: screening, confirmatory, and combination (confirmation mode includes a mandatory 15 minute wait lockdown before the confirmation test, if required).
  • Carrying case to house testing supplies
  • Portable design to allow for testing anywhere – both onsite and mobile
  • Applicable Markets: Employee Testing (DOT, Non-DOT, NRC, and DOE)
