• Q) Why can't I buy instruments on-line?
  • A) Because Intoximeters manufactures many different instruments as well as many different configurations of the same instrument, we believe it is best for the customer to discuss their specific needs with one of our expert staff members to determine which instrument will best fit their testing program.
  • Q) What is NHTSA?
  • A) National Highway Traffic Safety Administration

    NHTSA is an agency within the U.S. Department of Transportation. They are responsible for many things that are transportation-related. One of their functions is to evaluate and approve breath alcohol testing instruments.

    The U.S. DOT alcohol testing program requires the use of instruments on one of NHTSA's Conforming Products Lists (CPL).

    Conforming Products List - Evidential
    Conforming Products List - Screening
  • Q) What is the recommended method for cleaning a breath test instrument?
  • A) Use of a damp cloth is an acceptable method on exterior surfaces of the instrument. Special attention needs to be paid when cleaning the instrument so that moisture does not get onto the electronic circuit boards or into the internal sample path.

    There are certain disinfectant products that can be used. This is discussed more thoroughly in the attached document.
  • Q) How do I get information about state workplace drug and alcohol testing laws?
  • A) Most, if not all, states have regulations that govern workplace testing. Due to the fact that there are 50 different sets of rules and that they are often dynamic in nature, Intoximeters tries to, but is not always up to date on the latest requirements for each and every state. Many companies consult with legal counsel specializing in employment law when establishing a company policy regarding drug/alcohol testing.

    If your company is required to conduct drug and alcohol testing under one of the Federally mandated workplace alcohol testing programs (i.e.; the U.S. Department of Transportation, the Nuclear Regulatory Commission, or another federal agency regulation) it is probable that these federal regulations supersede state laws.
  • Q) What is an Accuracy Check?
  • A) Also called a "Calibration Check" or "External Calibration Check" or "Verification".

    The accuracy of any testing instrument should be checked periodically per the regulations governing your breath testing program. An accuracy check is a procedure used to test your instrument's ability to read a known standard within a given tolerance. This is accomplished by running a standard with a known alcohol concentration through the instrument's sampling system and verifying that the result is within an acceptable tolerance range of the expected value of the standard. It is much the same as running a sample on a subject but, in this case, the operator knows what result the instrument should produce. It is checking to see that a given known gas value registers correctly within tolerances defined by your testing protocol.

    This procedure is called an "accuracy check" and is sometimes referred to as a "calibration check" because it is a test (check) of proper calibration. If the reading produced by the instrument is outside of the acceptable tolerance, the device must be calibrated.
    Accuracy checks serve 2 purposes:
    Validating Subject test results. If your testing instrument reads the known standard gas within a defined tolerance range then it is reasonable to assume the device will provide accurate readings on a subject test. Any subject tests performed between two successful accuracy checks are, by default, accurate.
    Verifying long term accuracy. By documenting your accuracy checks in a calibration logbook, you can demonstrate the instrument's performance over time.
  • Q) How many drinks does it take to be over .080?
  • A) There are many factors which can affect an individual's alcohol concentration. The factors include, but are not limited to, how much alcohol is in the "drink", percentage of water composition in the user's body makeup, recent consumption of food. Try the Drink Wheel for an approximation.
