The indicator is colourless at room temperature and colours to blue when it is cooled below − 18 °C. To activate the indicator, place it in the freezer and hold it there for a minute. When it is taken out, it will continuously decolourise. The activation can be repeated.

In addition to reversible thermochromic indicators for low temperature, we also offer irreversible indicators for monitoring temperatures in the cold chain. The development is taking place within the framework of the project T-Sense Cold.

The indicator is coloured at room temperature and decolours above 35 °C. To activate the indicator, hold it between your fingers. If your fingers are cold, try warming them with a cup of hot tea. When the heat is removed, the indicator will colour continuously. The activation can be repeated.

This indicator represents a colour-changing coating that we developed for the Dom+ project and is being tested as one of the elements of a multifunctional, climatically active building envelope. We can produce reversible thermochromic indicators for a wide range of temperatures and applications.

The indicator is colourless at room temperature and turns black when heated above 75 °C. The indicator can be safely tested while preparing your tea or coffee. After pouring the hot water into a cup, hold the indicator to the hot surface until it changes colour. The colour change is permanent and the indicator can only be activated once. Do not touch a surface of the indicator and do not heat the indicator above 100 °C.

Our unique approach enables us to produce high temperature irreversible thermochromic indicators for a wide range of manufacturing control applications. The development is carried out within the framework of the T-Heat project.
