Apply where temperature monitoring is required.

Usage consideration

  • Do not rub the color changing part. This may cause abnormal color change.
  • Apply on a clean and dry surface.
  • Apply on flat surface. Temperature Label-F might drop from uneven applying surface.
  • Avoid applying on curved surface and bending indicators.
  • Do not cut Temperature Label-F. This may reduce the durability of product and cause abnormal color change.


Store unused indicators under room temperature and dark condition.  Avoid high temperature and excessive humidity.


Color Change
  • The color change temperature and its accuracy were determined in room temperature with 2-3℃/min of heating rate. Under special condition, color change temperature might be changed.
  • The performance of irreversible temperature labels which change color at 130℃ or higher may be changed if it is exposed to temperatures in the -10℃ from the specified temperature.

Applying label

  • Remove water, oil, rust and dust from the surface before applying labels. Contamination and uneven surfaces can cause labels to drop and abnormal color change.
  • Remove release film and apply where temperature monitoring is required and press the surface of label gently with finger or cloth. Strong rubbing might damage the label and affect performance (abnormal color change).
  • Apply labels on flat surface. Labels are not designed to apply on curved and corner surface.
  • Do not change shape of products. Cutting products with a cutter knife or re-shaping can reduce the durability and cause abnormal color change.


  • Do not use electromagnetic induction heating, for example, microwave oven, under high pressure condition and high vacuum condition.
  • Do not use Temperature Label-F under plasticizer* affected condition. When Temperature Label-F absorbs the plasticizer, indicator may change color and/or may impact adhesion of Temperature Label-F
    *Plasticizer may be contained in insulating coating of electrical cable, terminal cap and vinyl chloride resin.
