Testoterm Temperature strips can be connected to a wide range of surfaces and respond to particular increments in temperature by changing shading irreversibly inside 2 to 3 seconds. The temperature strips change color irreversibly when a certain temperature has been exceeded. The color does not change back.

Applications: for moving or tiny objects like circuit sheets, for long-term observing of capacity and transport temperatures, in research centers, in automobile innovation, in flight, and in astronautics.
