ColdMark

ColdMark is a single-use descending temperature indicator designed to protect sensitive products from freeze damage during storage and transit. By providing irreversible visual evidence of exposure to unacceptably low temperatures, ColdMark ensures reliable monitoring across the cold chain.

Once the pre-set threshold is breached, ColdMark changes color permanently from clear to violet, giving supply chain managers and quality control teams a clear, instant accept/reject decision point. This simple yet powerful solution helps reduce the risk of product loss and guarantees that compromised goods are not distributed.

Trusted for pharmaceuticals, vaccines, biologics, lab samples, and food shipments, ColdMark enhances cold chain visibility and supports regulatory compliance. Its straightforward design makes it cost-effective, easy to implement, and essential for industries where temperature integrity is critical. With ColdMark, businesses can maintain product quality, protect consumers, and strengthen cold chain accountability.
