Thermax Product Overview

The Thermax Irreversible Temperature Recording Label is a series of temperature test labels that will permanently record the highest temperature reached by the label.

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.

The temperature-sensitive elements are phase-change indicators that 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.
