ColdMark Freeze Indicators put you in control even after your product has been shipped. With ColdMark, your customer will know at a glance if the product has been exposed to damaging or extreme temperatures during shipping or storage. The ColdMark indicator accurately shows if your product has been exposed to cold below 32°F/0°C. This is done by its colorless indicator bulb turning to an irreversible violet color as temperatures rise above the indicator's response temperature. (Other response temperatures are also available.) More importantly, ColdMark is guaranteed to work within plus or minus 1 degree of this response temperature, the highest level of accuracy available in the industry.
