Ready-To-Use Indicators

Freeze Indicators

FREEZEmarker®, manufactured by Temptime®, is a single-use indicator that monitors exposure to freeze events. It provides an easy-to-read, irreversible visual signal when a freeze event at or below the response temperature occurs. 

Gauge Exposure to Freeze Events With Easy-To-Read Indicators

FREEZEmarkers display a clearly visible green circle and white checkmark to indicate when temperatures are above the response temperature. When exposed to temperatures at or below the response temperature, the green circle turns partially or completely white, obscuring the white checkmark, to warn that the temperature limit has been exceeded and the endpoint reached.
