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.
