PQ.1000 Power Quality Analyzer

About
The PQ.1000 is a handheld three-phase power quality analyzer designed for fast, non-intrusive field diagnostics in industrial and utility environments. Using external Rogowski coils or voltage-output CTs, it measures voltage, current, power, energy, harmonics, waveform distortion, swells, dips and unbalance without disconnecting circuits. With 32GB internal storage, Modbus-TCP communication and comprehensive power quality functions, it is ideal for commissioning, maintenance and power quality investigations.
