High Precision DC to 20kHz/1000A AC/DC Pull-through
Current Sensors with ±0.05% Basic Accuracy

Hioki pull-through AC/DC current sensors are best-in-class
devices for use with power meters, Memory HiCorders and high
performance oscilloscopes. The CT6865 is a DC to 20kHz/1000A
sensor, ideal for capturing current signals from switching
power supplies, inverters, power conditioners, etc.
