1.What is temperature indicator labels?

Temperature indicator labels are temperature monitors consisting of one or more small heat sensitive indicators sealed under a transparent heat-resistant windows.

2.Working principle of temperature indicator labels.

Temperature-sensitive labels with adhesive backing are composed of multiple white temperature indicating boxes, and the preset color-changing rated temperature of each box is different. When the external temperature of the ink reaches a certain temperature range, the internal structure of the ink undergoes a violent chemical reaction, so that the label presents a different color.

3.Features of temperature indicator labels.

Irrversible: The irreversible temperature label is a single-use indicator offer continuous monitoring and records a permanent, irreversible reading for the highest temperature attained . They help prevent breakdowns and shortened equipment life due to overuse or exposure to high temperatures.

White Turn Red

Reversible: The reversible temperature label can be used repeatedly. When the monitored temperature reaches or exceeds the preset rated temperature of the label, the label will quickly change color, and it can recover after cooling.

Difference between the irreversible and reversible temperature indicationg labels:
The reversible temperature color change bar can be changed back and forth as needed to indicate the current temperature. The biggest advantages of reversible temperature stickers is that they can be used repeatedly. The irreversible temperature sticker is a one-time use indicator that indicates that the specified pre-set temperature has been reached. Irreversible sticker is very useful when the operator is not monitoring in real time. At any time in the future, you can check the irreversible sticker to see if it has reached the specified temperature at that time.

4.Application of temperature indicating labels.
