3M™ MonitorMark™ Time Temperature Indicators solve the challenge of monitoring thermal exposure of temperature-sensitive products during transportation and storage.These indicators are an inexpensive and effective way to monitor product temperature exposure through the entire supply chain. They provide a non-reversible record of exposure above the specified temperature threshold that is accurate and easy to interpret.

• Inexpensive solution for monitoring product exposure to temperatures above the specified limit over a 1 week time period
• Self-adhesive backing for easy attachment to secondary packaging
• Easily-interpreted visual results
• Results indicate both exposure and relative time over which exposure occurred
• For accuracy, removable film activation strip starts the monitoring process
