WarmMark temperature indicators are now being used on COVID-19 test kits and vaccine trials in Europe.
WarmMark can monitor test kits required to remain frozen to avoid false negatives and meets CDC shipping guidelines.
The WarmMark is accurate and easy to use.
Use WarmMark -18°C / 0°F, for COVID-19 diagnostic test kits that need to remain frozen during shipment and storage.
Use WarmMark 8°C / 46°C for COVID-19 diagnostic test kits that need to remain refrigerated during shipment and storage.
For COVID-19 diagnostic test kits that need to be monitored for excursions both outside of frozen and refrigerated temperatures, please use COVID-19 TempControl.
WarmMark is a single-use, ascending time-temperature indicator which alerts users of exposure to unacceptable temperature conditions.
