Description

Hioki flat bandwidth current probes are best-in-class current sensors for use with Memory HiCorders and high performance oscilloscopes.

The 3274 supports wide DC to 10 MHz bandwidth signals and 150A of continuous high input, and is ideal for capturing transient current signals from switching power supplies, inverters, and motor controllers.

Key Features

  • Waveform observation across a wide band from DC to MHz
  • Connects directly to oscilloscope or Memory HiCorder BNC input terminal *1

*1 Connecting the device’s metal BNC terminal to a Memory HiCorder’s plastic BNC terminal may damage the plastic terminal or cause it to become misshapen.
