3M™ MonitorMark™ Time Temperature Indicator 9860B solves the challenge of monitoring thermal exposure of temperature-sensitive products during transportation and storage.
These indicators are an 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 25°F/-4°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.
