• Reversible indicator for cold temperatures
  Indicator is colourless at room temperature and becomes coloured when cooled down below the activation temperature. After heating, it becomes colourless again.
• Reversible indicator for high temperatures
  The indicator is coloured at room temperature and becomes colourless when heated above the activation temperature. After cooling, it becomes coloured again.

Reversible indicators can be used in a variety of applications for instant temperature control for functional or marketing purposes. In addition to indicators with conventional activation temperatures, we can also produce indicators with customised activation temperatures.
