Hioki portable power meters and analyzers are best in class power measuring instruments for measuring single to three-phase lines with a high degree of precision and accuracy. The PQ3100 is a comprehensive but easy-to-use power quality analyzer for monitoring and recording power supply anomalies, allowing their causes to be quickly investigated, and also for assessing power supply problems such as voltage drops, flicker, harmonics, and other electrical issues.


Key Features

• Record data including voltage, current, power, harmonics, and flicker simultaneously along a single time axis

• Measure up to 6000 A AC • Capture all power anomalies, including instantaneous outages, voltage drops, and frequency fluctuations, while simultaneously recording trend data

• Quick Set: Easy-to-understand on-screen guide for measurement procedures

• Bundled PQ ONE application software makes it easy to create reports

• Record waveforms for up to 1 second before and 10 seconds after an anomaly occurs

• Accurately measure DC currents over extended periods of time (with an AC/DC auto-zero current sensor)

• Directly supply power to connected current sensors
