Hioki portable power meters and analyzers are the 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. It is also for assessing power supply problems such as voltage drops, flickers, harmonics, and other electrical issues. Record data including voltage, current, power, harmonics, and flicker simultaneously along a single time axis. Capture all power anomalies, including instantaneous outages, voltage drops, and frequency fluctuations, while simultaneously recording trend data. 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 (with an AC/DC auto-zero current sensor).
