Oven Calibration

Irreversible High-Temperature 8-Point Labels/Indicators

  • Reliable proof that the product was maintained at the correct temperature
  • Save time and money due to costly recalls
  • Self-adhesive design
  • Labels are made up of a series of temperature-sensitive elements sealed between heat-resistant substrates with transparent windows.
  • Each element changes color distinctly as its rated temperature is met or exceeded. The changes to the label are irreversible, providing a temperature history of the surface being monitored. The labels will not delaminate when removed, allowing them to be attached to an inspection report to serve as a permanent record.
