TempDOT Freeze labels provide an irreversible, visual alert if temperatures fall below Freezing. The easy to see color indicator lets you make an immediate decision on whether or not products may have been damaged by the cold. These low cost labels are an excellent choice for shipping food, pharmaceuticals, biological samples or any products sensitive to freeze damage.

Freeze Check labels provide a quick, efficient and economical way to tell if the temperature of a product drops below freezing 32°F. The label`s indicator changes irreversibly from clear to white and the green check mark is no longer visible, so you can tell with a quick glance if the product has been exposed to sub-freezing temperatures. Designed with a flexible, self-adhesive label, they easily apply to any number of surfaces for an economical, yet high quality solution.
