WARMMARK ascending temperature indicators help determine if your products have gone above an acceptable temperature.

Single-use, irreversible ascending time-temperature indicator alerts users of exposure to unacceptably high temperatures.

Field activated by pulling a tab.

WarmMark time-temperature indicators provide a cost-effective tool for monitoring the temperature of your package. They are a single-use device that provide accurate, irreversible evidence of a temperature excursion that can be adhered directly to the product being monitored or located inside the packaging.

When the WarmMark is exposed to conditions above the activation temperature ±1°C; a red dye will begin migrating through the run-out window(s).

Run-out times are based on a temperature 2°C above the indicator threshold. If the temperature is greater than 2°C above the activation temperature of the device, the run-out will occur faster.

Standard MOQ is 100 pieces.
