The eight level label is our most popular irreversible indicator. It gives the largest possible area of adhesion and the most visible number of temperature cells.

The label comes in five ranges, A to E, with temperature ranges from 37° C to 260° C (99ºF to 500ºF). The label measures 51 x 18 mm (2.00" by 0.7") and carries temperatures in both Centigrade and Fahrenheit on the scale.

It is widely used in a variety of engineering applications from monitoring temperatures during transportation, providing evidence of temperature achievement in a thermal cleaning process and for running safety checks on machinery or warranted moving parts.

If an indicator has been exposed to a temperature in excess of its rating, it provides a tamper proof display of temperature achievement. It can be used for:

  • monitoring transportation and distribution
  • providing evidence of a thermal disinfection temperature achievement
  • confirming soldering temperatures
  • monitoring engine component temperatures for warranty claims
  • confirming temperature integrity in machine maintenance 
  • warning users that environmental conditions exceed temperature limits

When using these indicators, ensure we recommend they are kept only in refrigeration temperatures and NOT exposed to freezing conditions. The labels must be applied to a dry, clean surface to ensure proper adhesion. If placing the indicators in an environment where they can be exposed to any kind of aggressive conditions we recommend the labels are sealed in place on a clean dry surface with one or more layers of clear epoxy.

Please also note that touching the indicator may activate the lower temperature ranges on the indicators in summer months, especially if ambient temperature is above 25ºC.
