Testoterm self-adhesive temperature measurement strips are thin, temperature-sensitive pieces of film which change their color when the temperature exceeds a specific value. This makes them ideal for monitoring the temperature of products and processes where the temperature is not allowed to exceed a certain limit, i.e. for moving or small objects like circuit boards, for long-term monitoring of storage and transport temperatures, in laboratories, in automobile technology, in aviation and in astronautics.

The temperature strips in action

The temperature strips are available in booklets of 10. The strips are peeled off and applied to the object you wish to measure.

The strips have a temperature scale ranging from +37 °C to +65 °C which is divided into little white boxes. As soon as a specific temperature has been exceeded, the strip changes color in the relevant boxes in the space of 2 to 3 seconds. The temperature steps for the individual boxes are as follows: 37 °C, 40 °C, 43 °C, 46 °C, 49 °C, 54 °C, 60 °C and 65 °C.

When the strips change color, they do so irreversibly. When a certain temperature has been exceeded, the color does not change back again when the temperature returns to previous levels. This allows you to see that critical thresholds have been exceeded even when the temperatures have returned to the levels they were before the limit was reached. This makes them ideal for use in storage and transport.

We are also able to provide you with temperature strips for monitoring higher temperatures. The following measuring ranges are available:

• +71 °C ... +110 °C
• +116 °C ... +154 °C
• +161 °C ... +204 °C
• +204 °C ... +260 °C
