Power Quality Analyzer

Power Quality Analyzer

Power Quality Measurement

The PQPro™ is a portable 8 channel (4 voltage and 4 current) power quality analyser that can stream high resolution waveform and RMS data to high capacity removable SD memory cards. Sampling rate can be adjusted from 64 samples per cycle to 1024 samples per cycle. It's the most advanced power quality data logger and recorder instrument.

The PQPro™ is in a rugged weatherproof enclosure that can be left recording in all kinds of environments - from the top of a utility pole to the bottom of an underground mine shaft!

Data collected by the PQPro™ is analyzed by the PV II™ data analysis software. PV II™ is packed with powerful graphing and reporting features yet easy to use. Customize graphs - add data boxes, annotate with custom text and modify scaling. Automatic report generation with data tables and graphs. Flexible export functions plus many more features.
