3M™ MonitorMark™ Time Temperature Indicator 9861A solves the challenge of monitoring thermal exposure of temperature-sensitive products during transportation and storage.

These indicators are an inexpensive and effective way to monitor product temperature exposure through the entire supply chain. They provide a non-reversible record of exposure above the specified temperature threshold that is accurate and easy to interpret. The 3M™ MonitorMark™ Time Temperature Indicator works best when placed inside insulated shipping boxes near the temperature sensitive product, where it monitors the temperature and indicates not only if a product is exposed but also for how long. The large indicator window displays exposure, the smaller windows to the right indicate for how long temperature exposure took place, up to 48 hours. The 3M™ MonitorMark™ Time Temperature Indicator 9861A will show initial color in 24 hours or less when the temperature begins to rise above 50°F/10°C +1°C. When exposed to a constant temperature 2°C above the threshold temperature for a time period equal to the stated cumulative run-out time of 48 hours, the run-out distance will be within specification limits. Despite the best efforts to properly package, certify, and ship thermal-sensitive commodities, there are no guarantees that a product will make it through the shipping system intact. When a package is delivered physically intact, there is still no way to know if the contents were subjected to higher than acceptable conditions. When all packaging requirements have been followed and precautions observed, 3M™ MonitorMark™ Time Temperature Indicators add a critical layer of content security by providing a noticeable indication that the package and contents were exposed to damaging temperatures. This inexpensive indicator affixed to the inside of the container, near the contents, provides information to assist in estimating time and temperature exposure. The visual indicator clearly alerts the recipient that the contents may be compromised despite the physical condition of the package.
