We offer many models of data loggers for the measurement of DC voltage and DC current. There are units specifically designed for voltage and current measurements with probes that can be directly connected to the signal source--these models typically cost less and are easier to setup but offer less flexibility if your needs change. If you think your range of measurements may change in the future, a data logger with an external transducer will allow you to change the input range by connecting a different transducer. Also, if you need to log other signals in addition to voltage/current, or if a mix of DC and AC voltage/current needs to be monitored, a general purpose Universal Input Data Logger can be configured with appropriate transducers to enable the simultaneous measurement of multiple input signal types.

We offer several types of data logging systems that are suitable for measurement of AC voltage and/or current. We have AC Voltage/Current Data Loggers that come with built-in transducers to support a specific voltage and/or current range. We have models suitable for monitoring single and three phase AC signals up to 600 VAC and hundreds of amps. If you need to monitor AC signals outside this range or have to monitor a mix of AC and DC voltage and/or current inputs, we also 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.
