HIOKI AC CLAMP POWER METER CM3286-50

Quickly Check Current, Voltage, Power, and Power Factor
Detect Electricity Theft and Meter Tampering



Key Features

  • Display four parameters simultaneously
  • A handheld power meter that measures from 5 W of power and 60 mA of current
    Measure power ranging from 5 W at a low current of 60 mA to 360 kW
  • In addition to current, voltage, and power, measure simple integral power consumption and phase sequence
  • Features and functions deliver fast and efficient testing
  • Harmonic analysis from 1st to 30th order with GENNECT Cross (Wireless Adapter Z3210 is necessary)
  • Easily transfer measurement data to your smartphone or tablet by using our free app GENNECT Cross or to an Excel® file (Wireless Adapter Z3210 is necessary)
