The ShockWatch environmental indicators monitor temperature during shipping and storage, indicating whether goods have been exposed to unacceptable temperatures. This single-use WarmMark indicator is specifically designed to help shippers identify and correct gaps in their temperature-controlled supply chains. The result is increased knowledge of your product's environment when the product is out of your sight and out of your control. This ShockWatch WarmMark ascending temperature indicator is a simple solution for monitoring temperature-sensitive products. Simply pull the activation tab and begin monitoring your product. A white to red color change informs you when the temperature has reached unacceptable levels and your product quality may have been compromised.
