Knowing the correct temperature has been maintained is critical to the cold chain. The SpotSee FreezeSafe™ indicator provides accurate evidence if a product has experienced unacceptably low temperatures. This cost-effective solution allows you to add an indicator to every shipment or mount directly onto the product. Easy to use, FreezeSafe turns from clear to magenta when the temperature falls below its threshold. A simple visual check alerts the recipient if the temperature has been unacceptably cold.
