Feature: 1. There is no exposed metal conductor in the coil, adopt non-contact measurement method, which is safe and reliable. 2. It is small in size, light in weight, exquisite in appearance, soft and flexible, suitable for narrow environment and flat cable dense place. 3. It can detect AC leakage current, large current, high-order harmonic current, complex wave current, transient pulse current, phase, power, power factor, etc. 4. Wide measurement range, high accuracy, strong reliability, the hysteresis effect is not affected by the external electric field, and has a noise free frequency band (0.1 Hz-1 MHz). 5. The position of the wire is located in the center of the test wire coil, and the influence of position error is less than 0.3% FS. 6. It is widely used in electric power, communication, meteorology, railway, oil field, architecture, measurement research and teaching units, industrial and mining enterprises and other fields.
