Monitor the temperatures that your perishable, fragile, or sensitive goods are subjected to during transit. ShockWatch Environmental Indicators monitor temperatures during shipping and storage, acting as a dependable spoilage indicator, clearly showing whether goods have been subjected to unacceptable conditions.
Encased in a cylindrical tube, specially formulated fluids turn from clear to violet when exposed to temperatures below the predetermined activation temperature level. Five activation temperatures cover a broad spectrum of applications. Simply peel the release liner off the back of the indicator and apply the pressure-sensitive adhesive backing to any dry surface to activate and apply.
