Extech DL150 and DL160 voltage and current dataloggers
By Anthony Capkun
Extech Instruments introduced the DL150 single-channel and DL160 dual-channel true RMS AC voltage and current dataloggers. The compact tools are designed for electrical, industrial plant maintenance and predictive maintenance professionals who require extended recording of in-depth readings for electrical motors, components or circuits. The dataloggers measure and log AC voltage to 600V and current to 200A, with sampling rates ranging from 1/s to 1/24-hour period, and recording capacity of 100,000 (DL150) or 256,000 readings (DL160). Readings can be downloaded via USB for analysis, trending or exporting to Excel format. The two-line LCD displays time/date, current measurement and min/max values. The loggers can operate in both continuous (overwrite) or stop-when-full recording modes.
