Introducing the Hioki CT6904A and CT6904A-1 AC/DC Current Sensors – the perfect tool for accurate and efficient current measurement in research and development fields. With a best-in-class measurement bandwidth and high accuracy, these pass-through type current sensors can be connected directly to Hioki Power Analyzers and Memory HiCorders, and can also be used with Power Meters, Oscilloscopes, DMMs, and other instruments by using an optional sensor unit.

The CT6904A has a frequency bandwidth of DC to 4 MHz (Model CT6904A-1 is DC to 2 MHz) and a rated current of 500 A, making it an ideal choice for measuring large currents. Its excellent linearity of ±5 ppm and high Common-Mode Rejection Ratio (CMRR) of 120 dB (100 kHz) ensure that measurements are precise and reliable.

Designed to be used with instruments with a high input impedance of 1 MΩ or higher, the CT6904A and CT6904A-1 offer combined accuracy with Hioki power analyzers PW8001 and PW6001, which is specified in the instruction manual. The CT6904A comes with a cable length of 3 m (9.84 ft.), while the CT6904A-1 is build-to-order and comes with a longer cable length of 10 m (32.81 ft.).

Whether you’re measuring loss in high-frequency reactors, wireless charging systems, or EV inverter motors, the Hioki CT6904A and CT6904A-1 AC/DC Current Sensors provide accurate and efficient current measurement for all your research and development needs.
