Extech DL160 Dual Input True RMS AC Voltage/Current Datalogger

The DL160 is designed for professionals needing high-capacity, dual-channel logging of AC voltage and current with true RMS accuracy. It enables simultaneous measurement of either two voltages, two currents, or one of each, making it adaptable for monitoring complex circuits or comparative power-line diagnostics. The sample rate is user-programmable from 1 second through to 24 hours, allowing both short-term transient capture and long-term trend logging. Its memory holds up to around 256,000 readings in single-channel mode (or about 131,000 in dual-channel mode) ensuring extended deployments without interruption. The unit includes a built-in LCD showing time/date, current readings and Min/Max values, and supports USB PC connection via included software for exporting data into spreadsheets for further analysis. The logger is supplied as a complete kit with sensor modules for voltage and current, test leads/alligator clips, USB cable, power adapter and batteries, so it is ready for immediate deployment in the field.
