Certification
All PosiTector UTG probes include a Certificate of Calibration. For
organizations with re-certification requirements, instruments may
be returned at regular intervals for calibration.
DeFelsko recommends that customers establish calibration
intervals based upon their own experience and work environment.
Based on our product knowledge, data and customer feedback, a
one year calibration interval from either the date of calibration, date
of purchase, or date of receipt is a typical starting point.
