Freeze-tag® is an electronic freeze indicator designed to detect and record temperature drops below freezing point during storage and transport. The device allows for rapid identification of whether a product has ever been frozen, even after the temperature has returned to a safe level.
Freeze-tag® is particularly suitable for vaccines, pharmaceuticals, medical bioproducts, and other temperature-sensitive products, helping to minimize the risk of damage from freezing in the cold supply chain.
