testoterm - Temperature strips (+98.6 to +149 °F) 

Order-Nr.  0646 0108

  • Measuring range +98.6 to +149 °F

  • Self-adhesive temperature strips

  • Change color in 2 - 3 sec when thresholds are exceeded

  • Ideal for monitoring temperature of small/moving objects / long-term monitoring of transport/storage temperatures

Testoterm self-adhesive temperature strips can be applied to a variety of different surfaces and react to specific increases in temperature by changing color irreversibly within 2 to 3 seconds.


Product Description

Testoterm self-adhesive temperature measurement strips are thin, temperature-sensitive pieces of film which change 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 / long-term monitoring of storage/transport temperatures and in laboratories/automobile technology/aviation/astronautics.

The temperature strips in action

The strips are available in booklets of 10. They are peeled off and applied to the object’s surface.

The strips have a temperature scale ranging from +98.6 to +149 °F which is divided into little white boxes. As soon as a specific temperature has been exceeded, the strip changes color in the relevant boxes within 2 - 3 seconds.

The temperature strips change color irreversibly when a certain temperature has been exceeded. The color does not change back. This allows you to see that critical thresholds have been exceeded even when temperatures have dropped again. 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:

  • +159.8 ... +230 °F
  • +240.8 ... +309.2 °F
  • +321.8 ... +399.2 °F
  • +399.2 ... +500 °F
