The WarmMark Duo temperature indicators 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 severity of temperature excursion.
Higher temperatures will cause run-out to occur faster than stated.
