3-Channel AC/DC Power Meter for Single-Phase to 3P4W Equipment such as Motors, Inverters, Power Conditioners, and Power Supplies Hioki benchtop power meters and power analyzers are best in class power measuring instruments for measuring single to three-phase lines with a high degree of precision and accuracy. The PW3337 series measure power on the full range of electrical equipment, from single-phase devices such as battery-driven devices and household electronics to industrial use and three-phase electrical equipment over 3 input channels. The power meters provide coverage from DC to inverter frequencies with support for voltages up to 1000 V and direct-input currents of up to 65 A, and can also measure currents of up to 5000 A using an optional current sensor. PW3337 (basic model) • PW3337-01 (with GP-IB) • PW3337-02 (with D/A output) • PW3337-03 (with GP-IB and D/A output)

3-Phase 4-Wire Portable Power Demand Analyzer 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 3169-20 and 3169-21 are 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). Note: Optional current sensor is necessary to measure current or power parameters. To store measurement data, use only the guaranteed PC cards sold by Hioki.
