The LOG.IC is a single-use USB temperature data recorder designed to be low-cost and help optimise the cold chain by alerting manufacturers, handlers, and shippers when a product has been exposed to temperature levels beyond a specified threshold. Unlike other temperature recorders that limit users to one download before stopping the recording process, the data logger allows users to scan and view the tag data repeatedly, allowing measurements to be taken at any point of the cold chain. To meet different specific requirements, the LOG.IC can be customised for applications such as monitoring product core temperatures with a stainless steel probe, inside validated packaging with a ribbon cable, ice gel packs or extreme cold with a dry ice solution.
