These indicators are adhesive labels that control the time a product is exposed to a temperature higher than adequate. Its use is simple, just stick it on the product or its packaging and activate it by removing the upper tab and the protective film sheet.
Once activated, if the temperature is higher than that marked On the label, the control points change their color sequentially, thus indicating the exposure time at that temperature. Each point is regulated to carry out the complete color change, once the amount of time prescribed for each point has been accumulated. In this way, we can know the time of exposure to critical temperatures, seeing which points have changed and which have not. Some of the models have a single point, so they only measure a period of time.
The color change is irreversible and stops or resumes, depending on whether or not the marked temperature. In this way, it correctly records the time of exposure to temperature, even intermittently. The fact that the change is permanent allows a posteriori to see the level of compliance with the cold chain.

Supply: Packs of 100 units
Dimensions: 46 x 19 mm
Accuracy: +/- 1ºC (2ºF)
Change times are based on at a temperature 2 ° C (4 ° F) above the indicating threshold. If the temperature is greater than 2 ° C (4 ° F) above the device's activation temperature, the change may occur more quickly.
Resistant to water, detergent, alcohol, aliphatic hydrocarbons and some aromatics. It is not recommended for use in contact with active solvents such as ketones, esters and some chlorinated hydrocarbons.
Excellent stability to ultraviolet light and resistance to high temperatures
Acrylic adhesive that provides excellent adhesion to most smooth surfaces.
WarmMark time and temperature indicators are most effectively used when affixed directly to the product being monitored or when placed inside the container or the box. Indicators should not be placed directly on cooling gel packs, freezer plates or ice packs, etc., as this will result in measuring the temperature of the packaging material components rather than the product temperature. < br />
In exceptional cases, the temperature indicators are glued on an external packaging to monitor the temperature conditions of the chamber or container.
