What does a Time/Temperature Indicator (TTI) strip measure?

A Time/Temperature Indicator (TTI) strip measures the accumulated time and temperature exposure of a product throughout its storage and handling. These indicators are designed to monitor temperature variations to ensure that perishable products, such as food and pharmaceuticals, remain within safe temperature ranges that prevent spoilage or degradation.

TTI strips change color or show some visual cue in response to specific temperature thresholds over time, providing a visual indication of whether the product has been exposed to conditions that could compromise its safety and quality. This functionality is critical in industries where maintaining the cold chain is vital, as it helps ensure that products are stored and transported under optimal conditions.

The other options do not align with the primary function of TTI strips. They do not measure humidity or weight, nor do they provide nutritional breakdowns. Instead, their focus is singularly on tracking temperature and time, making them essential tools in food safety management and quality assurance practices.
