Temperature Sensitive Labels
Temperature labels are temperature monitors consisting of one or more small heat-sensitive indicators sealed under transparent, heat-resistant windows. They have advantages over other temperature monitoring solutions in that they don't require a power source to work, and so can provide accurate feedback in challenging circumstances. The labels allow you to quickly check if a product or area has been subjected to compromising temperatures, and so are sometimes used in where perishable or sensitive materials are stored. They are commonly found in pharmaceutical, food and medical applications.
What types of temperature sensitive labels are there?
Reversible - reversible temperature labels can change back and forth as needed to provide an indication of the present temperature. One advantage of the reversible labels is that they can be used over and over again.
Irreversible - irreversible self-adhesive temperature monitors consist of one or more heat sensitive indicators sealed under transparent, heat-resistant windows. The center of the indicator circles will turn black at the temperature ratings shown on the label, resulting in a one-time usage indication that the specified temperature has been reached.
