Freeze Indicators

Gloved hand holding Zebra TransTracker® C FREEZEmarker®

Gauge Exposure to Freeze Events With Easy-To-Read Indicators

FREEZEmarker®, manufactured by Temptime®, is a single-use indicator that monitors exposure to freeze events. It provides an easy-to-read, irreversible visual signal when a freeze event at or below the response temperature occurs. FREEZEmarkers display a clearly visible green circle and white checkmark to indicate when temperatures are above the response temperature. When exposed to temperatures at or below the response temperature, the green circle turns partially or completely white, obscuring the white checkmark, to warn that the temperature limit has been exceeded and the endpoint reached.

  • Ensure Customer Confidence

    FREEZEmarker from Zebra is an easy-to-understand, visual, freeze event indicator. It helps identify when freeze sensitive items have been exposed to a potentially damaging temperature event.

  • Save Costs Associated With Reships

    FREEZEmarker and TransTracker® work together to help you save costs associated with reships. Protect your margins from re-shipments of products where there is uncertainty if the product has been exposed to damaging freeze events during cold chain transport or storage.

  • Customise Your Solution

    Zebra freeze indicators come in several different response temperatures allowing a broad range of freeze events to be identified. They can also be branded and placed inside multiple unit secondary packages or shipping boxes with consumer information included.
