Large Selection

We offer a variety of data loggers that are suitable for measurement of AC voltage and current. We have models that come with built-in transducers to support a specific voltage and/or current range.

If you need to monitor DC Voltage or Current, please click the following link to our: DC Voltage and Current Data Logger Page . If you have to monitor a mix of AC and DC voltage and/or current inputs, we have a great selection of Universal Input Data Loggers that can be outfitted with transducers to measure almost any type of input - from mV and uAmps to thousands of volts or amps - click the following link for our Universal Input Data Loggers .

Transducer Support

If you need to measure voltages and currents that are beyond the standard input ranges of these data loggers, we can provide transducers that are suitable for up to hundreds or thousands of amps that work with our general purpose data loggers that allow measurement of most voltages and currents found in residential, commercial or industrial applications. These loggers also allow the measurement of other input signals types besides voltage and current.

For more information on transducers, go to our tutorial page for Voltage and Current Measurements. Please call us at 800-956-4437 and we will help you design a system to meet your exact requirements.
