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 3193-10 is a 6-channel power meter for testing any type of circuit ranging from single-phase lines to three-phase four-wire lines. Based on the voltage, current, and active power measurements, the power meter calculates and displays reactive power, apparent power, power factor, phase angle, and efficiency. It also provides a wide range of measurement functions including frequency measurement function, peak measurement function, current integration, active power integration, analog outputs, monitor outputs.
