Waltham, MA, USA (Vocus) December 7, 2010

Extech Instruments, makers of the best handheld test and measurement tools, announces the new DL150 single-channel and DL160 dual-channel true RMS AC voltage and current dataloggers. The compact new tools are designed for electrical, industrial plant maintenance, and predictive maintenance professionals who need extended recording of in-depth readings for electrical motors, components, or circuits.

The compact true RMS dataloggers measure and log AC voltage to 600V and current to 200A with sampling rates ranging from 1 per second to 1 per 24-hour period and recording capacity of 100,000 (DL150) or 256,000 readings (DL160).

Readings can be easily downloaded via USB to a laptop or PC for analysis, trending, or exporting to Excel format using the dataloggers’ software application. 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.

The versatile DL150 single-channel datalogger offers users three operating modes: Normal, Peak and Capture. In Capture mode, triggers can be defined to capture in-rush and transients lasting less than 0.25 milliseconds. The Peak button briefly displays peak values while still operating in normal mode.

The two-channel DL160 is useful for simultaneously logging both the current and voltage of one component or one metric from two components. A channel button alternates the display between each channel’s values.

The Extech DL150 and DL160 are CAT III-rated. Each comes complete with current clamps, test leads, USB cable, Windows® compatible software, universal AC Adaptor, and 3.6V Lithium battery. Both are available now from stocking distributors with suggested retail prices of $249.99 and $299.99 respectively.
