3M™ MonitorMark™ Time/Temperature Indicators monitor products for temperature fluctuations through the entire supply chain. They provide a non-reversible record of temperatures that are accurate and easy to interpret.
3M™ MonitorMark™ Time/Temperature Indicators are available in a variety of time and temperature ranges, and are used to monitor the cold chain for perishable food products, vaccines, blood and many other applications.
Product Construction • Rectangular, flat laminate with layers of paper, film, adhesive and other components • Blue compound, run-out to estimate how long the product was above the threshold temperature • Removable film activation strip • Pressure-sensitive adhesive that bonds to almost all clean and dry surfaces
Uses • Monitoring temperatures of temperature-sensitive products during transportation and storage such as frozen or refrigerated foods, drugs, vaccines, medical diagnostic kits, blood, blood products, and intraocular lenses • Typically placed inside insulated shipping boxes near temperature sensitive products • The indicators monitor temperature exposure, not product quality. Their purpose is to signal when product quality should be checked due to temperature fluctuations
