AC True RMS Data Loggers

RMS can be defined, with respect to power, as the DC equivalent of an AC voltage. All of the loggers here are capable of measuring True RMS. Use these devices to measure AC line voltage, mean blood pressure and/or flow from a pulsatile pressure or flow waveform, RMS voltage and current from a variable speed motor, and more.
