Indicator labels with changing colour surfaces for pH and temperature
Indicator labels with changing colour surfaces for pH and temperature

Indicator labels accompany production processes

These technical labels react to conditions
The completion of a process stage is shown by indicator labels that have colour change surfaces with individual fields where the colour change is reversible or irreversible.
For example, colour indicators react with certain pH values or in a defined temperature range.

In our example on the right, the orange area changes irreversibly to light yellow following contact with acid.
The white area in the thermometer becomes irreversibly black above a certain temperature.
