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 (up to 800 A special order available) sensor, ideal for capturing current signals from switching power supplies, inverters, power conditioners, etc. The sensor uses flux gate detection within the zero flux method to deliver outstanding linear properties, enabling it to maintain high precision even at low current levels.
