Thermax ® Irreversible Temperature Recording Strips
Product Description: A series of temperature test labels that will permanently record the
highest temperature reached by the label.
What They Are:
These self adhesive labels consist 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 exceeded. The changes are irreversible, providing a temperature
history of the surface being monitored. The labels will not de-laminate when removed for reference
and can be attached to an inspection report to serve as a permanent record.
How the labels work:
The temperature-sensitive elements are phase-change indicators which use the sharply defined
melting points of a series of specially purified organic chemicals to give the unique, high precision,
color change effects. Each temperature element uses a different chemical compound and is made
separately by applying a coating containing the chemical to a special absorptive paper substrate.
When the rated temperature is exceeded, the chemical melts and is absorbed by the substrate,
causing a permanent color change. Up to ten elements can be combined together on a single label.
