The Hioki CT6873 pass-through type AC/DC current sensor can be connected directly to several Hioki devices. It has a frequency bandwidth of DC to 10 MHz and a rated current of 200 A. It is used for R&D, quality evaluation, manufacturing, and maintenance in markets such as wireless charging systems, inverter motors for industrial equipment, power conditioners for PV, and quick charging facilities for EVs.

High-accuracy sensors use the "zero flux method (flux gate detection type)." High-frequency currents are detected with the winding (CT method), and DC to low frequency currents are detected using a "flux gate." Flux gate detection delivers outstanding linear properties, and can measure currents of a wide range of magnitudes with high accuracy.

The flux gate components used for DC detection have very low offset over a wide temperature range due to their operating principle, resulting in high accuracy and excellent temperature stability. It is ideal for measurements that require high accuracy, such as Power analyzers and Power meters. It can be used for measurement such as inverter efficiency, inverter output power, reactor/transformer loss, and long-term DC measurements.
