4E (50-110℃)

Combo of four temperature indicators at 5℃ intervals for more accurate monitoring purpose.

Four indicator at 5℃ of intervals are printed on a single label to monitor three different threshold temperatures. Unlike other types, 4E is specially designed to carry indicators with 5℃ increments. Because of this 4E can monitor the temperature more accurately and is best suited for the temperature control of electrical and electric devices. Each indicator changes to different color when reaches to set temperature.

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. THERMO LABEL® 4E might drop from uneven applying surface.
  • Avoid applying on curved surface and bending indicators.
  • Do not cut THERMO LABEL®4E. 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.

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 THERMO LABEL®4E under plasticizer* affected condition. When THERMO LABEL® 4E absorbs the plasticizer, indicator may change its color and/or may impact adhesion of THERMO LABEL® 4E.
