3M™ Freeze Watch™ Indicators provide a reliable measure of temperature exposure. They are ideal for monitoring pharmaceutical products, including vaccines, medicines, and chemicals that run the risk of being damaged when exposed to freezing temperatures during shipment and storage.

The patented design of 3M™ Freeze Watch Indicators consists of a highly sensitive indicating liquid inside a specially designed ampule. When exposed to freezing temperatures, the ampule fractures, releasing a liquid. The liquid irreversibly stains a paper behind the ampule, indicating that product has been exposed to unacceptable temperatures so product quality testing should be performed.
