3M Monitor Mark Temperature Indicator Strips

3M MonitorMark Time Temperature Indicators add an important temperature exposure measure that extends beyond your plant to your customers' delivery dock.

MonitorMarkTM Time Temperature Indicators not only signal when a threshold temperature has been exceeded, but provide an easy-to-read visual signal to estimate the minimum amount of time a product has spent above the threshold temperature.

MonitorMarkTM indicators feature a high contrast indicator that turns blue as a result of exposure to rising temperatures. The indicator is irreversible, providing a permanent record of temperature exposure even after temperatures return to acceptable levels.

Placed inside secondary shipper boxes of temperature-sensitive products during shipment and storage, the indicators provide information to assist in estimating time and temperature exposure.
