HIOKI Current sensors for Power Logging and Monitoring
Reliable current sensing for on-site maintenance
HIOKI’s general-purpose current sensors are ideal for power quality analysis, current logging, and AC/DC measurement up to 100 kHz. They combine dependable performance with compact or flexible form factors at a practical price.
Use the CT7131 for cabinet-level measurements, or choose flexible Rogowski coils like the CT7045 for installations in tight environments. For broader current and frequency ranges, the CT7736 offers robust AC/DC measurement performance.
Most sensors use HIOKI’s PL14 connector and can be linked to HIOKI DAQ systems. They also connect to BNC instruments using the L9910 adapter.
