Delivering High Accuracy Performance Over a
Measurement Band 40 Times Broader than Legacy

Hioki pull-through AC/DC current sensors are best-in-class devices
for use with power analyzers,, Memory HiCorders and high performance
oscilloscopes. The CT6904 is a DC to 4 MHz/500A sensor, ideal for
capturing current signals from switching power supplies, inverters,
power conditioners, etc.
