TESTO 0646 0077 - Mini temperature indicator testoterm, +199 ... +224 °C, 10 pcs.

The self-adhesive testoterm mini-indicators can be stuck to the measured object and respond to temperature rises within 2 to 3 seconds with a color change.


The temperature mini-indicators are self-adhesive, temperature-sensitive foils that react with a color change to specific temperature overshoots. They are ideal for temperature monitoring of products and processes where a specific temperature should not be exceeded, e.g. for moving or small objects or for long-term monitoring. The temperature mini-indicators are supplied in a booklet of 10 each. They can be easily detached from the booklet like stickers and stuck onto the measured object.

The coloring is irreversible: once the temperature has been exceeded, the mini-indicator does not change color even if the temperature drops again. This means that critical temperature overshoots can be read even after a long time.

Product advantages:

• self-adhesive mini-indicators for temperature monitoring
• color change when limit value is exceeded within 2 to 3 seconds
• optimal for temperature monitoring on moving or small objects and long-term monitoring
