NiGK CryoMark thermal indicator

Many types of goods, including food, pharmaceuticals and chemical reagents, must be kept cold while in storage and transit. If goods have been shipped on ice or under refrigeration, it is important to know that those cold temperatures were maintained. Traditionally this has been done with the use of electronic data loggers; however, data loggers are not practical for many applications.

CryoMark, from NiGK, Japan, is a disposable chemical indicator that can be included in every cold shipment. If temperatures have been exceeded, the indicator will change colour to red. This allows the receiver to confirm that the goods have arrived in good condition, without the need to send back a data logger to the shipper for download and analysis.

The product is easy to use: simply activate and place inside the packaging next to the goods. There are different versions for different temperature cut-offs, so whether goods are frozen or just refrigerated, there will be a suitable CryoMark available.
