Hioki 9709 high-precision sensors to view waveforms or to use with power meters (for AC/DC). Wide-bandwidth and high-precision AC/DC current sensors achieve high accuracy measurement of both small- and large-current signals. They can be used for a wide variety of applications in the fields of electric and hybrid electric vehicles, inverters and other devices, alternative energy sources such as solar power and fuel cells, as well as home electronic appliances and system equipment.
