Hioki 3275 Clamp On Probe
Hioki flat bandwidth current probes are best-in-class current sensors for use with Memory HiCorders and high performance oscilloscopes.
The Hioki 3275 supports wide DC to 2 MHz bandwidth signals and 500A of continuous high input, and is ideal for capturing transient current signals from switching power supplies, inverters, and motor controllers.
