Time and Temperature Indicator
The 3M MonitorMark can be used for any temperature-sensitive product.
Indicators monitor exposure to temperature, not quality. The purpose of a Time Temperature Indicator is to show when the quality of a product should be inspected.
3M MonitorMark is generally used to monitor:
- Drugs or vaccines
- Kits for medical diagnosis
- Blood substances
- Ophthalmic solutions
MonitorMark indicators show color when exposed to a threshold temperature.
Time Temperature indicators do not only signal when a threshold temperature has been exceeded. But also provides an easy-to-read indication on the amount of time a product has spent above the threshold. MonitorMarks feature a high contrast indicator that turns blue when exposed to rising temperatures. The indicators are irreversible, therefore providing a permanent record even after temperatures return to acceptable levels.
When monitoring exposure to freezing temperatures, we suggest using 3M FreezeWatch indicators.
The 3M MonitorMark Time Temperature Indicator is a rectangular flat laminate containing layers of paper, film, adhesive and other components.
The heart of the indicator is a porous strip. One end is positioned over a reservoir containing a blue chemical with a desired melting point. Before activation, a removable activation strip separates the indicator track from the reservoir. The paperboard layer over these parts has viewing windows. The strip is topped with a protective film. An adhesive on the bottom of the strip allows attachment to most clean, dry surfaces.
