WarmMark

WarmMark® Temperature Indicator is a reliable, single-use, time-temperature monitoring device that provides clear, irreversible visual evidence of exposure to temperature excursions above a defined threshold. Designed for simplicity and effectiveness, WarmMark helps ensure cold chain compliance by immediately alerting handlers and recipients to potential spoilage, degradation, or compliance failures.

Lightweight and easy to use, WarmMark requires no special equipment and can be quickly activated and affixed inside a shipment. This makes it an ideal choice for pharmaceutical, biologic, food, and clinical trial logistics, where maintaining temperature integrity is critical.

By offering visible confirmation of temperature breaches, WarmMark enhances supply chain oversight and supports regulatory compliance, helping protect product quality and patient safety. With its proven performance and global use across sensitive industries, WarmMark is an essential solution for companies seeking simple, cost-effective, and reliable temperature monitoring during storage and transit.
