Hioki 3275 Clamp On Probe Wideband Current Probe for Oscilloscopes

Hioki flat bandwidth current probes are best-in-class current sensors for use with Memory HiCorders and high performance oscilloscopes. The 3275 supports wide DC to 2 MHz bandwidth signals and 500A of continuous high input.

The probe is designed with an electrostatic shield to reduce the effects of electric fields, making it ideal for measuring in environments in which the probe will be subjected to the effects of nearby magnetic fields, such as locations with high-voltage switching control equipment such as an inverter or motor.

Paired with the zero-flux method, a proprietary thin-film Hall element makes possible high-performance current sensors.

Wideband current sensors use the "zero flux method (Hall element detection type)" to measure. High-frequency currents are detected with the winding (CT method), and low frequency currents including DC are detected with the "Hall element."
