⬜⬛ WarmMark® TTI Indicator 32°F
The WarmMark® TTI Indicator provides permanent visual evidence when temperature-sensitive products are exposed above 32°F (0°C). When activated by temperature exposure, the indicator physically changes from white to black, generating a permanent, irreversible record of the maximum temperature exposure. Its adhesive backing allows easy attachment directly to products, packaging, cartons, or shipping containers.

Arming & Use:
1. *All WarmMark breach window(s) should be white prior to arming the device.
2.Before arming, the WarmMark indicator should be placed in an environment at least 5°C (9°F) below the WarmMark’s activation threshold temperature for a minimum of 30 minutes. (For WarmMark Duo, the indicator should be at least 5°C (9°F) or cooler for a minimum of 30 minutes.)
3. To arm the WarmMark indicator, fold up and pull out the indicator’s activation tab until the tab and barrier film have been completely removed.
4. If using a WarmMark indicator with an activation threshold temperature below the ambient temperature, immediately place the indicator in the environment to be monitored to avoid activation.
5. Remove the adhesive liner from the WarmMark and adhere the indicator to a clean, dry surface.
