Knowing the correct temperature has been maintained is critical to the cold chain. The SpotSee FreezeSafe™ QR indicator provides accurate evidence if a product has experienced unacceptably low temperatures. Easy to use, FreezeSafe QR turns from clear to magenta, light blue to dark blue, or light grey to dark grey when the temperature falls below its threshold. A simple visual check alerts the recipient if the temperature has been unacceptably cold. Upon scanning the QR code, the condition, time, location, and serial number are saved to the SpotSee Cloud.
How it Works

FreezeSafe QR senses environmental temperature that your shipment is subject to
-
