Voltage Output Sensor for Leak Current Measurements
Hioki current sensors are best-in-class devices for accurately capturing
a wide range of current levels. The 9657-10 is a voltage output clamp
sensor for measuring leak current. The high-permeability magnetic
material of the sensor’s core and magnetic shield enables
high-precision measurement of very weak currents.
