Freeze-tag Indicator (-0.5°C / 60 minutes)
Description
The Freeze-tag monitors the temperature of its environment and shows you on the display if there
has been an exposure of below -0.5 °C / +31.1 °F for over 60 minutes.
IMPORTANT:
The Freeze-tag monitors temperature exposure and not the product quality.
Its purpose is to signal if product quality evaluation/testing is required.
