Thermax Temperature Indicating Labels

Thermax Temperature Indicator Sticker

Thermax temperature indicator sticker is a fast and simple temperature monitoring system based on proprietary color change technology.

Thermax Temperature Indicator sticker is uniquely designed to immediately deliver accurate and reliable readings consistently – in a variety of applications or environments. Featuring a self-adhesive backing, Thermax sticker can be easily and quickly affixed to any surface. These are available in 10 Level strips, 8 Level strips, 6 Level strips, 5 Level strips, 4 Level strips, 3 Level strips with different temperature ranges.

These are self-adhesive labels that can be quickly affixed to any surface that change in color from silver to black. Options include level strips, mini strips, encapsulated indicators, level microstrip, and clock indicators.


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 which is usually black. When the rated temperature is exceeded, the chemical melts and is absorbed by the substrate, causing a permanent color change to black. Up to ten elements can be combined together on a single label.
