the product timestrip® plus duo line is created with vaccines in mind, as they indicate two ascending temperature breaches, both the higher and lower thresholds. this is a double action temperature monitoring in one, costeffective device. it is a cumulative breach indicator with readings for excursions above 10°c, in day ranges from 3 to 14, with a secondary indicator to show immediate excursions above an upper temperature breach point of 34°c. the device has in depth information with pushbutton simplicity. by removing the ambiguity of temperature abuse across time and temperature thresholds this allinone indicator can help prevent the unnecessary wastage of expensive medicines and vaccines.
