  1. Question

    jeffhannah – May 19, 2023

    If I blow a breathalyzer every morning for 40 days on the Alco sensor 3 but different Alco sensors and on the 35th day I blow a .001 what are the odds of that being correct and how much alcohol would be in my system?

      Hi Jeff.
      There would be .001 alcohol detected in your body. A .020 result is equal to one drink. I don’t understand your question regarding odds. Too many variables to assume and I am not a statistician.

      I guess my question would be if I blew a .001 on a breathalyzer, and it was only accurate up -/+ .005 could that .001 be considered a negative test for alcohol?

      It depends upon your company’s alcohol testing policy. In the world of DOT testing a negative test result is less than .020. In a company that is not regulated by federal testing regulations and where there a is zero tolerance (not very many have this policy), anything above .000 is considered a non-negative. Consult with your testing policy.

  2. Question

    Jason Carnell – September 15, 2023

    How can temperature impact the results of the test? For example, what if the air temperature is lower recommended 59 degrees?

      No. Temperature does not impact the amount of alcohol the device measures.

  3. Question

    Jason Carnell – September 15, 2023

    Are you supposed to continue holding down the test button after the suspect has provided a sample? If not, how can that impact the test results?

      Holding down the test button is not required but it doesn’t hurt anything either. Simply depress the button and then let go. Pressing the button opens up the sampling valve and draws in 1 cc of the subject’s breath. Holding down the button for an extended period of time does not impact the test result. The sampling valve quickly opens and then closes back.
