High Heat Alert

The data logger might report one thing, but the actual condition in a particular place in a trailer, in a particular position on a pallet and in specific place in the box may tell a different story. CTI BlindSpotz™ High Heat indicator technology alerts, at the product level, if the temperature has been too high. 



Allows easy sorting of suspect food items and won’t reset if the product returns to normal refrigeration temperatures. Combine with Freeze Alert, and you won’t miss a potentially dangerous food safety event. Contact CTI for more.
