3-Phase 4-Wire Portable Clamp-on Power Meter to Record Power Usage Trends for Energy Conservation, ISO14001 Testing, Equipment Diagnosis, and Harmonics Analysis

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 3169 is clamp on power meters designed to measure demand and harmonics, which are important for energy management, as well as basic electrical parameters such as voltage, current, power, power factor, and integrated power (watthours).

Key Features

• Simultaneously measure demand and harmonic waveforms that share the same voltage line over 4-circuits • Save data to a PC card • High-speed and continuous processing to measure individual waveforms • High-speed D/A output for analog graph recording (Model 3169-21)
