The WarmMark Duo Time/Temp Tag offers a two-in-one feature to allow monitoring exposure above two rated temperature thresholds.

The indicator records exposure and duration to temperatures above 10°C (50°F) from 3 to 14 days while providing an extra window to record a brief temperature spike above 34°C (93°F).
