The Data Loggers category at Roshanex offers instruments that record readings over time. It currently lists the Kyoritsu KEW 5020 3 Channel AC Current/Voltage Data Logger and the Uni-T UT330C USB Data Logger.

Electrical engineers use the Kyoritsu model to track current and voltage on a supply, for example when they study load patterns. The Uni-T logger connects over USB, so you can move the saved data to a computer. Both tools help when you need records without watching a meter all day.
