Testo 0646 1071 etichette indicatrici di temperatura testoterm +71 °C, confezione da 50

Irreversible temperature indicator labels that permanently change colour from white to black when the surface reaches +71 °C. Each pack contains 50 self-adhesive labels, providing a simple and reliable way to monitor temperature exposure during transport, storage, or processing.

Advantages

The irreversible colour change ensures a permanent record that the temperature threshold has been exceeded, even if the product later cools down. The self-adhesive backing allows quick attachment to a wide range of surfaces, and the compact size makes them suitable for use in confined spaces.
