Time temperature indicator

A time temperature indicator (TTI) is a device or smart label that shows the accumulated time-temperature history of a product. Time temperature indicators are commonly used on food, pharmaceutical, and medical products to indicate exposure to excessive temperature (and time at temperature).[1]

In contrast, a temperature data logger measures and records the temperatures for a specified time period. The digital data can be downloaded and analyzed.
