Coldmark® Temperature Indicators

ColdMark temperature indicators

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. Refrigeration equipment is not always reliable, and temperature can vary in a trailer, stack of pallets, or warehouse. Your products may pass through multiple handlers during the distribution process, possibly enduring delays and substandard storage. When you use ShockWatch temperature indicators, you can monitor the temperature of every shipment and know whether the duration of exposure was long enough to compromise product safety and efficacy.
