Temperature Label-4E

Temperature Label - 4E

A combination of four temperature indicators at 5℃ intervals for more accurate monitoring

Label and package
Color sample

Number of elements: Four
Temperature range: 50~110℃
Content: 20pcs/pkg
RoHS compliant

Four indicators at 5℃ intervals are affixed to a single label to monitor four different threshold temperatures. Unlike other types of labels, 4E is specially designed to for indicators with 5℃ increments. 4E can monitor temperatures more accurately and is best suited for temperature control of electronic and electric devices. Each indicator changes color when the set temperature is reached.

Apply where temperature monitoring is required.


    • Do not rub the color-changing part. This may cause abnormal color changes.
    • Apply on a clean and dry surface.
    • Apply on a flat surface. The THERMO LABEL® 4E might fall off if applied on an uneven surface.
    • Do not bend the indicator or apply to a curved surface.
    • Do not cut the THERMO LABEL®4E. This may reduce the durability of the product or cause abnormal color changes.


Color Change
  • The color-change temperature and color-change accuracy refer to the temperature and degree of accuracy at completion of a color change after heating from room temperature at a rate of between 2 and 3°C/min under normal pressure. The actual color-change temperature may differ depending upon heating conditions.
  • The temperature-indicating elements of irreversible temperature labels may show slight coloration even before temperature increases, but performance will not be affected and it will be obvious when the color changes at the specified temperature.

Affixing the Label

  • Be sure to clear the surface of all water, oil, rust, dust, and dirt. Dirty or uneven surfaces can result in abnormal color changes or cause labels to come off.
  • When applying the label, peel off the release liner and put the label on the object by pressing it down gently with your hand or a cloth. Do not rub or scratch the label too strongly to avoid inaccurate color changes caused by damage or deformation.
  • Apply the label on a flat surface to avoid inaccurate color changes.
  • Do not alter the shape of the label. Modifying the label, for example by cutting it with a utility knife, may affect the label’s durability or lead to inaccurate color changes.

Usage and Storage Environments

  • Do not use the product in high-pressure or high-vacuum environments, or in microwave ovens or other induction heating devices, as this could lead to inaccurate color changes.
  • Store in a cool dark place prior to use. Products specified as requiring cold storage should be kept refrigerated.
  • NiGK Corporation will not accept any liability for damages incurred as a result of using the product or applying measurements given by the products.
