Hioki CT6845A AC/DC Current Probe

Hioki CT6845A AC/DC Current Probe

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.

Replacing the discontinued Hioki CT6845 500 A AC/DC, PL23 terminal and Hioki CT6845-05 500 A AC/DC, ME15W terminal current sensors.
