3-Phase 4-Wire Portable Power Quality Analyzer to Detect, Measure and Record Power Quality Issues, Harmonics, Demand, Inrush and Power Transients




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 3197 is a handheld power quality analyzer for monitoring and recording power supply anomalies, allowing their causes to be quickly investigated. POWER QUALITY ANALYZER 3197

3197 main unit only

Note: Optional current sensor is necessary to measure current or power parameters.


Key Features

• Single-phase 2-wire/single-phase 3-wire/three-phase 3-wire/three-phase 4-wire

• Catch power quality problems on the fly, before they catch you

• Record measurement data on internal memory for easy transfer to a PC via USB

• Analyze measurement data on a bundled PC aplication software

■ Basic specifications (Accuracy guaranteed for 1 year, Post-adjustment accuracy guaranteed for 1 year)
