See Handling & Use Guidelines for proper pre-use conditioning. When kept within specified range the indicator track is white. Upon exposure to temperatures exceeding the specified trigger temperature, blue coloring appears at the left edge of the first viewing window and gradually moves left to right to the end of the track. The rate of the blue color movement is dependent on the temperature.
Monitoring temperature exposure of temperature-sensitive products during transportation and storage (for example drugs, vaccines, medical diagnostic kits, blood, blood products, and intraocular lenses) Typically placed inside insulated shipping boxes near the temperature sensitive product The indicators monitor temperature exposure, not product quality. Their purpose is to signal when product quality should be checked due to temperature exposure.

- (100) Time Temperature Indicators
MonitorMarkTM Time Temperature Indicators can be used to monitor any product exhibiting time temperature abuse sensitivity. They are used as part of the secondary package to monitor storage and transportation conditions. These simple to use and easy to read indicators signal when product quality should be checked. TheMonitorMarkTM Time Temperature Indicators monitor exposure not product quality. Some typical applications include monitoring of drugs and vaccines, medical diagnostic kits, blood sub- stances and ophthalmic solutions.
To prevent premature response, MonitorMarkTM Time Temperature Indicators (including dual temperature indicators) must be conditioned prior to removing the activation strip and activating the indicators. This insures that the response chemical is solid and not liquid prior to removing the activation strip. Condition indicators for a minimum of two hours in a suitable refrigerator, freezer or chamber at or below the temperature shown in the product table.
Once conditioned and ready for use, the indicators can be maintained at any temperature below their critical temperature.
Note: It is the indicator that must be cooled to the conditioning temperature listed in the chart not the product that is going to be monitored. The product need only be maintained below its critical temperature.
After proper pre-use conditioning, the monitoring process is started by simply pulling the side tab up and removing the activation strip. This allows contact between the reservoir pad and the end of the porous wick indicator track. At this point the indicator track (visible under the viewing windows) is a plain white color. Upon exposure to temperatures exceeding the critical response temperature, the chemical in the reservoir melts and begins to migrate along the track. Thus, blue coloring first appears at the left edge of the first viewing window and gradually moves left to right to the end of the track. The rate of the blue color movement is dependent on the temperature.
The appearance of any blue color in the indicator's first window signals the indicator's pre-set threshold temperature has been exceeded.
The extent of color movement ("runout") through the indicator's windows provides an estimate of the minimum amount of time spent above the threshold temperature. A short exposure at a relatively high temperature will produce coloration comparable to a longer exposure at a lower temperature.
