Vibration Analysts, Inc. provides the technical training courses listed below. These courses are available at your facility and will soon be offered at our future training facility located two hours north of Las Vegas:

Training and Certification

  Vibration Analysts Inc. is approved and authorized to provide ISO Category I, II, III, and IV certification training courses. To schedule any of these courses on-site, call us at 815-742-1793.


"BEST VALUE" Training:                                                                                                  We offer a combined Category I & II certification course. This fast-paced course is packed with technical information, but is intended for studious employees with no prior experience. This course is five days long (Monday - Friday) and the exam is proctored the following Monday, giving students time for self-study.


The advantages of this course include:
  • An unlimited number of employees can attend the training at no additional cost. (Books and exam fees are per attendee.)
  • This combined course costs less and your employees spend less time away from the plant, compared to sending two employees to attend these courses separately (as shown in the table below).
  • Employees bypass Category I and become qualified as Category II analysts.
