Time-temperature active tag
WarmMark®, WarmMark® Duo, WarmMark® Long Run SHOCKWATCH

WarmMark® is an environmental indicator. Affixed directly to your products' packaging, this reliable temperature sensor provides indisputable visual evidence of exposure to unacceptable temperature levels, protecting product quality throughout the entire shipping and handling process.

With the WarmMark® temperature indicator, a proprietary red dye is released onto a blotter to clearly indicate when your shipment is exposed to temperature levels above your predetermined level, creating a permanent and immediate indication of the duration of exposure. Activation of the device is simple — remove the tab and barrier film and apply to a dry surface on your product or packaging

The WarmMark® Duo monitors the exposure and duration of exposure of a product that exceeds two activation temperature levels.

The WarmMark® Long Run utilizes the same chemistry proven in the WarmMark Indicators while allowing for a longer exposure to temperatures that exceed the threshold level.
