The WarmMark Duo temperature indicators are single use devices that provide accurate, irreversible evidence of any above temperature deviation allowing you to make smarter decisions across the cold chain.
The WarmMark Duo temperature indicators are ascending time temperature indicators that alert users of exposure to unacceptably high temperature conditions and indicates the duration of temperature exposure at two different activation temperature levels, 10°C and 34°C in the one indicator.
WarmMark Duo features:
- Monitor for the length of time above 10°C and for brief excursions above 34°C
- Know if a product has been exposed past a threshold and check for high temperature spikes
WarmMark Duo window run out times:
|Window 1||Window 2||Window 3||Window 4|
|10°C||3 days||8 days||14 days||–|
|34°C||–||–||–||Within 30 mins|
* Run-out times are based on a 2°C excursion above the response temperature. Readings are affected by the severity of the temperature excursion.
Higher temperatures will cause run-out to occur faster than stated.
