FreshLoc Truck and Trailer Loggers, attached to the roof of a truck or trailer, monitor and record  the ambient temperature inside. The data is stored until the truck comes within range of a FreshLoc Reader, when it automatically downloads, providing a complete temperature log of the trip.

Within range of a FreshLoc Reader:
The FreshLoc Logger generates reports, graphs and alerts in real time. If temperature readings exceed customer parameters, an alert is sent to designated personnel via cellphone.

Outside the range of a FreshLoc Reader:
The loggers read and store temperature reports until the truck arrives within range of a FreshLoc Reader.
