Time temperature indicator labels designed to monitor temperature of products during shipping, storage or processing. Self-adhesive temperature indicator labels apply directly to product, package or carton. When activated, these irreversible temperature indicators change color once response temperature is exceeded. Red indicates if exposure was for a brief, moderate or prolonged period of time. With these irreversible temperature indicators you can see at a glance if a temperature abuse has occurred, providing permanent records for quality assurance purposes.
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.
The WarmMark should be located where it will be
visible to the receiver of the monitored shipment.
The WarmMark can be adhered directly to the
product being monitored or located inside the
Minimum Order of (50) WarmMark Labels. Used in transportation and long term storage.
