These self-adhesive reusable temperature labels provide a safe, accurate, easy-to-read means for monitoring temperatures. Indicating strips use liquid crystal technology to display the current temperature at an economical cost. The strip will turns a green color when ambient temperature is reached. Shelf life: 1 year after date of purchase.

• Non-toxic / non-hazardous temperature measuring alternative
• Easy to read and unbreakable

09035-41 Irreversible 1 Point Temperature Label, 260°C/500°F; 50/Pk by Digi-Sense

Labels are made up of a series of temperature-sensitive elements sealed between heat-resistant substrates with transparent windows. Each element changes color distinctly as its rated temperature is met or exceeded. The changes to the label are irreversible, providing a temperature history of the surface being monitored. The labels will not delaminate when removed, allowing them to be attached to an inspection report to serve as a permanent record. Ideal for use in the food, automotive, molding and metal working industries. Accuracy is ±1.8°F below 212°F and ±1°F above 212°F. Shelf life: 1 year after date of purchase.

• Used as a quick inspection tool that the product is in usable condition during the shipping and receiving process
• Save time and money due to costly recalls
• Self-adhesive design
