Irreversible Temperature Indicator Card

Irreversible temperature indicator cards utilize thermosensitive materials that undergo a permanent color change at specific temperatures to record temperature. When the ambient temperature reaches or exceeds the set threshold, the color patches on the card transition from their initial state to a final color and cannot revert. These indicator cards are used to monitor whether items have experienced excessive temperatures during transportation, storage, or use, and are commonly applied in fields such as food, pharmaceuticals, and electronic components.
Selection
When selecting irreversible temperature indicator cards, it is essential to consider the temperature range of the actual application scenario to ensure their thresholds cover the monitoring requirements. Pay attention to the response time and accuracy of the indicator cards to match the thermal sensitivity characteristics of the monitored items. Check the adhesion and durability of the cards to adapt to different surfaces and environmental conditions. Confirm the distinctiveness and stability of the color change for easy observation and recording. Refer to relevant industry standards or specifications to ensure compliance with application requirements.
