Sharply defined melting points of a purified organic chemical provide unique, high precision temperature sensitive phase change indicators with 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 to black.
Offering precise readings, these irreversible temperature labels combine:
- Defined melting points– Giving high accuracy with the ability for you to specify exact requirements based on your needs
- Individually Coated– Allowing you to design your label giving you accurate and clearly defined results
- Permanent Color Change– Allowing you to keep records for quality control and due diligence or records abuse of your products in the field
Irreversible vs Non Reversible Temperature Labels
Both terms describe the same technology. An irreversible or non reversible temperature label permanently records when a specific temperature has been reached. Once the color change occurs, the label cannot return to its original state. The terminology varies across industries, but the function remains identical, providing a permanent visual record of temperature exposure.
In contrast, reversible indicators can change back when temperatures drop, making them useful for continuous monitoring but not for evidence of heat exposure.
How Irreversible Temperature Labels Work
Each SpotSee label contains a purified organic compound that melts at a precise temperature. When that threshold is reached, the compound is absorbed into the substrate and produces a dark color change. This transformation provides a clear, permanent visual signal that the temperature limit has been exceeded. Because every temperature point uses a different compound, the labels deliver reliable and repeatable performance across a wide range of applications.
The technology is based on controlled phase change, not electronics or external power, ensuring consistent accuracy even in demanding environments.
