The label on the back of the logger allows for important shipping information to be recorded. The TDL-10 can record over 8,000 measurements, and the easy to use TDL-SC software makes retrieving data simple. The TDL-10 can easily be started and stopped from a PC, delayed to start up to thirty days in advance, or begin to start by a push of a button.
