ColdMark descending temperature indicators are single-use devices that provide accurate,irreversible evidence of a below-temperature deviation allowing you to make smarter decisions across the cold chain. 

ColdMark is designed to help shippers identify and correct gaps in their cold chain. The ColdMark turns from clear to violet when the temperature goes below a predetermined threshold.
