Temperature Indicators WarmMark®

Self-adhesive labels that change color when a certain temperature is reached.

Categories: ,

Description

These time-temperature indicators alert users of exposure to unacceptably high temperature conditions and the cumulative amount of time above the temperature threshold. Without them, a cold chain breach may go unnoticed resulting in a compromise in your product’s quality.

They provide a cost-effective tool for monitoring the temperature of your package. They are single-use devices that provide accurate, irreversible evidence of a temperature excursion. With the information you gather from these indicators, you can make smarter decisions across your cold chain.

Advantages

  • Delivers irreversible evidence of exposure to unacceptable temperature conditions
  • Provides cost-effective solution for last mile monitoring
  • Enables easy accept/reject decisions to be made
  • Assists in verifying the adequacy of the cold chain packaging
  • Aids in compliance with regulatory guidelines
  • Saves money and space since field armable indicators require no special packaging or storage
  • Available in pre-armed configurations for high volume packaging environments

Specifications

  • Temperature Accuracy ± 1°C
  • Storage Conditions Store below the response temperature and below 55% relative humidity for optimal shelf life.
  • Shelf Life 2 years from date of sale

Run out times are based on a constant temperature 2°C above the indicator threshold. Exposure to higher temperatures will result in faster run out

Use Instructions

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.
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 a threshold temperature below the ambient temperature, immediately place the indicator in the environment to be monitored to avoid early activation.
5. Remove the adhesive liner from the WarmMark and adhere the indicator to a clean, dry surface.
a. The WarmMark should be located where it will be visible to the receiver of the monitored shipment.
b. The WarmMark can be adhered directly to the product being monitored or located inside the packaging.
6. Any sign of color in the breach window(s) after arming, including light pink, pink, or red, is a sign of temperature excursion equal to or above the time and temperature specification
