How to Use the WarmMark
®
WarmMark is a single-use, ascending time-temperature indicator which alerts users of exposure
to unacceptable temperature conditions.
Arming & Use:
(WarmMark Short Run, Long Run, Duo)
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.
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.
Interpreting the WarmMark:
When the WarmMark is exposed to conditions above the
indicator’s activation temperature ±1°C (±2°F), a red dye
will begin migrating through the run-out window(s).
Run-out times are based on a temperature 2°C (4°F)
above the indicator threshold. If the temperature is
greater than 2°C (4°F) above the activation temperature
of the device, the run-out will occur faster.
Storage Recommendations:
WarmMark indicators should be stored in a cool dark
place below the activation temperature of the indicator
and between 35-55% relative humidity (RH).
* If any red is visible on the WarmMark prior to arming, please contact ShockWatch or your local distributor.
