Testoterm measuring strips, mini-indicators
Self-adhesive, temperature-resistant films
With heat-sensitive elements for temperature monitoring and control
Ideal solution for measuring tasks for which standard temperature measuring devices cannot be used:
- In hard-to-access spaces
- On moving parts
- For long-term monitoring
- On small objects etc.
Short response times of 2 seconds
Simple handling

Heat-sensitive elements respond to certain temperatures
On reaching the temperature value in question, the colour irreversibly changes from light grey or yellow to black within 1s
This black colouring is retained even on subsequent cooling

Quickly and easily record high temperatures with these heat-sensitive labels from Testo. The strips are scaled in small increments with boxes that change colour as each temperature level is reached, making them simple to read. This change of colour permanently marks the strips even after cooling, enabling you to accurately record and provide proof of temperatures in long-term applications. Use them for machine testing, scientific research or monitoring controlled environments.

• Quick response time of 2 to 3 seconds for swiftly recording temperatures
• Broad temperature measuring range of +161°C to +204°C for use in high-temperature applications
• Flexible label material bends around curved surfaces such as tubes and pipes
• Supplied in a handy pack of 10 to ensure you'll have enough on hand

• Research laboratories
• Transport and logistics
• Aviation industry
• Chemical processing plants

These labels are easy to apply thanks to their self-adhesive backing. Simply peel off the backing and stick the label vertically on your surface. To record temperatures accurately, make sure there are no air bubbles trapped under the label.
