The TempDot Freeze Indicator provides an irreversible visual alert once the temperature descends below the defined threshold value of the label.
- The label is always active and prior to use must be shipped, stored and handled in an environment above threshold temperature of 32°F/0°C. Keep the label between 68°F to 77°F (20°C to 25°C). For optimal shelf life store at 39°F (4°C). DO NOT FREEZE.
- Remove the adhesive liner from the back of the label and adhere it to the product or package. Note: the product to be monitored must be above the 32˚F/ 0˚C threshold.
- Once the label is exposed to temperature below the 32˚F/ 0˚C threshold, the green dot in the middle will irreversibly change to red.
