Temperature Indicators

ColdMark and WarmMark are inexpensive but highly effective environmental temperature indicators.  These provide a permanent, tamper proof record of essential data with regard to temperature within your insulated container.  Once attached to the product, and placed in the insulated cavity, these reliable indicators offer visual evidence of the temperature to which the product has been subjected.


Encased in a protective tube, specially formulated fluids change from a clear to violet color when subjected to an environment below the starting activation temperature level.  Four different activating temperatures offer a broad variety of applications. To activate: Remove the release liner from the back of the indicator and apply the pressure-sensitive adhesive backing to any dry surface on your product.


The temperature indicator has a proprietary red dye that is released onto a blotter to clearly indicate when your product is exposed to temperature levels above your starting activation level.  This creates a permanent, tamper proof record with immediate indication of the duration of exposure. To activate: Remove the tab and barrier film and apply to a dry surface on your product.
