ETCR025K Split Type High Accuracy
ETCR025K Split Type High Accuracy


ETCR025 Split Type High Accuracy Leakage current Sensoris used for measurement of high accuracy AC current, leakage current, high order harmonic current, phase, power energy, power, power factor. Adopt the latest CT technology. It is portable, large clamp design, no need to disconnect the measured circuits, non-contact, safe and fast. It can be connected with phase detection analyzer, industrial control equipment, data recorder, oscilloscope, harmonic analyzer, electric power quality analyzer, high precision digital multi-meter, etc. Widely applied in electricity, communication, meteorology, railway, oilfield, construction, measurement, scientific and research teaching unit, industrial and mining enterprises.
ETCR025 Split Type High Accuracy Leakage current Sensor’score is made of special alloy, adopt the double magnetic shielding techniques, can almost shield the influence from external magnetic field, to ensure the high precision, high stability and high reliability of perennial uninterrupted measurement.
