Temperature label-LI

Color transition simulation

Large, visible and durable single-point indicator best for interpretation from a distance

Number of element:One
Temperature range:40~250℃
Content: 40pcs/pkg
RoHS compliant

Reversible Irreversible Semi-reversible


The φ8-11mm(φ11mm for Ll-40~105 and φ8mm for Ll-110~250)size indicator has the great visibility from a distance. This highly durable type is widely used for a wide area of applications for temperature monitoring indoors or outdoors. In power company, this type is used for transmit equiment to prevent accident and to optimize security control by controlling temperature. Above all, this type is the best choice for the outdoor temperature monitoring from a distance because of its bigger element size and outstanding durablity.

Product feature

  • 1point temperature indication
  • Irreversible, single-use
  • Temperature range: 40°C to 250°C
  • Color changing element is completely sealed in heat-resistant film to avoid environmental affect such as water, chemical, oil etc…
  • Self-adhesive and easy to apply on various location. (The back side is coated with heat resistant adhesive material)

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 LI under plasticizer* affected condition. When temperature label LI absorbs the plasticizer*, indicator may change color and/or may impact adhesion of temperature label LI. *Plasticizer may be contained in insulating coating of electrical cable, terminal cap and vinyl chloride resin.
