Hioki benchtop power meters and power analyzers are best in class power
measuring instruments for measuring single to three-phase lines with a
high degree of precision and accuracy. The PW3337 series measure power
on the full range of electrical equipment, from single-phase devices
such as battery-driven devices and household electronics to industrial
use and three-phase electrical equipment over 3 input channels. The
power meters provide coverage from DC to inverter frequencies with
support for voltages up to 1000 V and direct-input currents of up to 65
A, and can also measure currents of up to 5000 A using an optional
current sensor.
