Product Description

testoterm measuring points are self-adhesive, temperature-sensitive films that respond by changing colour when a certain temperature is exceeded. They are ideal for monitoring the temperature of products and processes where a specific temperature must not be exceeded.


Using the measuring points

The measuring points are supplied in a book of 50. Just like stickers, they can be easily removed from the book and affixed on the measurement object.

As soon as the specific temperature point (+77 °C) is exceeded, the measuring point changes colour within 2 to 3 seconds. The colour change is permanent: once the temperature has been exceeded, the measuring point will not change back to neutral even if the temperature drops again. This means that a critical temperature increase can be identified even after an extended period.

Are you looking for a testoterm measuring point with a different temperature point? Measuring points are available for the following temperature points:
  • +65 °C
  • +71 °C
  • +82 °C
  • +110 °C
  • +121 °C
