ColdMark
ColdMark® Descending Temperature Indicators
Visual Assurance for Cold Chain Integrity
Know if your shipment went too cold—before it’s too late.
ColdMark temperature indicators provide clear, irreversible evidence of exposure to unacceptable low temperatures. When a shipment goes below the specified threshold, the indicator turns from clear to violet, alerting you to a potential cold chain breach.
Ideal for pharmaceuticals, chemicals, biologics, food, and other temperature-sensitive products, ColdMark empowers you to make confident accept/reject decisions at a glance—without complex tools or expensive electronics.
