Transcat is your source for power data loggers that deliver critical information. Our instrument selection features the best tools for energy studies and power quality logging, with basic to advanced functionality. Portable dataloggers can automatically display and store: voltage, current, power, harmonics and associated parameters. Instruments can report dips, swells, and inrush currents. Applications include load studies and equipment assessments, plus identification of harmonics issues and power problems. Our power quality devices can also diagnose the condition of two- or three-phase networks while storing snapshot, trend and alarm data. We have power meters, loggers, and analyzers built by true measurement pros, such as Fluke, AEMC, Hioki and Extech.
