CT6844A – AC/DC Current Probe

Overview

Hioki’s clamp type AC/DC current sensors can be connected directly to Hioki Power Analyzers and Memory HiCorders. Also, it can be connected to Power Meters, Oscilloscopes, DMMs, etc. by using an optional sensor unit.

Use with an instrument with a high input impedance of 1 MΩ or higher.
